Question

For the regular square pyramid, suppose that the sides of the square base measure 12 ft each and that the altitude is 8 ft in length.

1.Find the lateral area L (in square feet) of the pyramid.

2.Find the total area T (in square feet) of the pyramid.

3.Find the volume V (in cubic feet) of the pyramid.

Answer 1

Draw and label a diagram.

By Pythagoras the slant height is 10 ft.

L = 4((0.5)(12)(10)

T = L + 12²

V = (1/3)(12²)(8)
