To find the volume of a square-based pyramid, use the formula _V_ = _A_(_h_/3), where _V_ is the volume and _A_ is the area of the base. 1. Collect the Essential Information Collect, measure or calculate the height of the pyramid and the length of one side along its base. ...
That is, the square of the slant height minus the square of one-half the width of the base equals the square of the height of the pyramid. Does a square-based pyramid have 4 faces? It may appear that a square pyramid has 4 faces, but it is more accurate to say it has five. The...

is 456 feet. This last platform is thirty two feet eight inchessquare, and if to this were added what is necessary to complete the pyramid, the total height would be 479 feet. Each side of the base, measured round the stones let into the rock, is 763 feet 5 inches, and the perimeter...
We are given a square base that has an area of 144 ft2. Let s be the side length. The area of a square of side s is s2 . Thus we have s2 = 144. Since 144 is just 122, then s = 12 ft. We are asked for the perimeter of the square base. The perimeter of the base of ...
