An equilateral triangle
Triangle
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted △ABC. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane. In other wor…

How do you figure the amount of concrete in a triangle?
Calculating volumeRemember the formula for calculating volume is: Volume = Area by height. V = A X h.For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.
What is the formula for calculating concrete?
Use the formula. Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

What is the correct mix for concrete?
The safest bet for any concrete mix is four-two-one: four parts crushed rock; two parts sand; and one part cement. The four-two-one mix, obviously, has seven parts. Conveniently, when mixing concrete, the ratio can be mixed on any range of scales.
How do you calculate concrete in meters?
Concrete wall calculation For a wall made of concrete the calculation is practically the same: height(ft) x width(ft) x length(ft). For example, to calculate the volume in cubic meters for a wall with a height of 2m, width of 20cm and length of 4m, you need to multiply 2 x 0.2 x 4, which equals 1.6 m3 (cubic meters).

How is concrete made?
Concrete can be purchased in multiple forms, including in 60 or 80-pound bags, or delivered in large amounts by specialized concrete mixer trucks. Proper mixing is essential for the production of strong, uniform concrete. It involves mixing water, aggregate, cement, and any desired additives. Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid. Some concretes are even designed to harden more quickly for applications that require rapid set time. Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls.
How long does it take for concrete to cure?
The process of concrete hardening once it has been placed is called curing, and is a slow process. It typically takes concrete around four weeks to reach over 90% of its final strength, and the strengthening can continue for up to three years. Ensuring that the concrete is damp can increase the strength of the concrete during the early stages of curing. This is achieved through techniques such as spraying concrete slabs with compounds that create a film over the concrete that retains water, as well as ponding, where concrete is submerged in water and wrapped in plastic.
Why is concrete mixing important?
Proper mixing is essential for the production of strong , uniform concrete. It involves mixing water, aggregate, cement, and any desired additives. Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid.
What is cement used for?
Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time . While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters.
Is concrete time sensitive?
Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid. Some concretes are even designed to harden more quickly for applications that require rapid set time.
How much concrete is in a yard?
Concrete volume is measured in cubic yards. When poured on a perfectly level surface, one cubic yard will cover 27 square feet at one foot thick.
How many cubic feet is a concrete yard?
Most concrete purchases will be made in cubic yards, which equates to 27 cubic feet. For example, a project measuring 10 ft in length by 10 ft in width with a depth of 3.5 in will be just over 1 cubic yard. The equivalent to a single cubic yard in metric measurements would be roughly 0.76 cubic meters.
How much does a concrete slab weigh?
A solid, unbroken slab of concrete weighs about two tons (or 4,000 pounds) per cubic yard. Breaking up concrete roughly halves the total weight per cubic yard to about one half ton (or about 2,000 pounds).
Should I buy bagged concrete or have ready mix delivered?
CEMEX specializes in ready mix concrete formulated to your exact specifications and delivered to your job site. Larger jobs can be completed much more easily and efficiently when you order ready mix concrete by the yard. Ready mix concrete is ideal for large patios, driveway renovation, pool decks, home foundation slabs, parking lots, and new sidewalk construction. If you’re just doing some DIY maintenance around your home property, a yard of concrete is going to be far more than you’re able to use. In these cases, it makes more sense to purchase bagged products and mix them yourself. Examples of smaller projects include minor repairs (curbs, sidewalks, stairs, etc.), ramps, small patios, and setting fence posts.
How to find cubic yards of concrete?
Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness.
How much to add to slab for concrete?
Rule of thumb: add 1 / 4 " to the thickness of your slab for your slab concrete budget. This assumes you have the job evenly graded to the right depth, and the grade is well compacted.
Why is it important to check the size of the concrete on your footing?
The excavator may have dug too deep, or it may have rained and footings needed to be dug out deeper to reach firm soil. So it is important to check a variety of spots on your footing and get an average size. Then use the calculator to figure the amount of concrete needed.
What is bagged concrete used for?
Bagged concrete is ideal for: Pouring small slabs for sidewalks or patios. Setting posts for fences or mailboxes. Making repairs to foundation walls, walkways or steps.
How many linear feet are there in a 6' step porch?
The porch also has 9 linear feet of 6" step. So enter in the footing calculator, 6" depth by 12" width (always figure steps with a 12" width) by 9' length. This totals .17 cubic yards.
How many yards of concrete do you need to order?
Many ready mix companies will have a minimum order of 1 yard, and will charge shortage fees when ordering partial batches. The average truck holds between 9 and 11 yards total. If your project requires more concrete, multiple trucks will be necessary.
Can you order concrete by yard?
Larger jobs such as driveways are easier to complete when ordering concrete by the yard, rather than trying to mix bag after bag by hand. For smaller jobs, like a walkway, modest patio or footings, you should calculate the number of concrete bags instead.
