The three-dimensional shapes (3D shapes), known as solid shapes, are the shapes that have three dimensions such as length, breadth and thickness. The two distinct measures used to define the three-dimensional shapes are volume and surface area. Generally, the three-dimensional shapes are obtained from the rotation of two-dimensional shapes. Thus, the surface area of any 2D shapes should be a 2D shape. If you want to calculate the surface area of solid shapes, we can easily calculate from the area of 2D shapes.

How to find area of a shape?
Think back to area again and recall how one would find it. It is simply found by multiplying the base by the height of the shape. Although the formulas for area differ from shape to shape, the general idea is still the same: base times height. Similarly, the volume of a shape formula can be boiled down to one idea: area times height. Although there are slight differences between the formulas for different objects, the idea of an area multiplied by its height is consistent for most.
