Question

The Great Pyramid of Giza is located in Egypt. It has a height of about 460 ft, and width of its square base is about 55ft..

Answer 1

(a)

the area of a square = s² ( where s is the length of side )

area = 55² = 3025 ft²

(b)

the volume (V) of a pyramid is calculated using

V = $\frac{1}{3}$ × area of base × height

   = $\frac{1}{3}$ × 3025 × 460

   = 463 833 ft³ ( to nearest cubic foot )
