Question

The great Pyramid outside Cairo, Egypt, has a square base measuring 756 feet on a side and a height of 480ft

Answer 1

Answer:

V = 3,386,880 cubic yards

V = 91445760 cubic feet

V = (1/3) · b2 · h  so  1/3  x 756^2 x 480 = 91445760 ft^3

Answer = 91445760 ft^3

Step-by-step explanation:

converting feet into yards

let  

1 yard = 3 ft  

1 ft = (1/3) yard  

a = 756 ft = 756*(1/3) yards the length of the side of the square base

h = 480 ft = 480*(1/3) yards the height of the pyramid

 

a.) the volume of the pyramid V = (a^2*h)/3 = (a^2*h)(1/3)

V = (756*(1/3))^2*480*(1/3)*(1/3)

V = 3,386,880 cubic yards
