A steel forging in the shape of a regular pyramid weighs 214.5 pounds. The base of the pyramid is a square with 7.71-inch sides. Compute the height of the forging to the nearest tenth of an inch. The steel in the forging weighs 490.5 pounds per cubic foot.
What will be an ideal response?
Volume of pyramid: 214.5/490.5 = 0.4373 cu ft = 755.6697 cu inArea of base = 7.71 x 7.71 = 59.4441 sq inHeight = 3 x Volume/Area = 38.1 in
