It’ll weigh around 58 lbs based on MDF’s density of 37.5-50 lb/ft³, whereas a similarly sized spruce plywood sheet would weigh approximately 41 lbs, given that spruce plywood has a much lower average density of 460 kg/m³.. Why Is MDF So Dense? MDF sheets typically consist of 82% wood …

WebIt is estimated that the volume of the Antarctic ice sheet is about 25.4 million km 3 (6.1 million cu mi), and the WAIS contains just under 10% of this, or 2.2 million km 3 (530,000 cu mi). The weight of the ice has caused the underlying rock to sink by between 0.5 and 1 kilometre (0.31 and 0.62 miles) in a process known as isostatic depression.
