+252 Becky visited the Great Pyramid of Giza. She learned that the pyramid was originally 481 feet tall and its square base had sides measuring 751 feet in length. Becky wants to know the volume of the pyramid. What is the volume of the pyramid?
A) 1.2 x 10^5 ft^3
B) 4.5 x 10^7 ft^3
C) 3.6 x 10^5 ft^3
D) 9.0 x 10^7 ft^3
+9479 volume of pyramid = (1/3)(area of base)(height)
area of square base = 751 * 751 ft2 = 564001 ft2 Plug this in for area of base.
Plug in the height given in the problem.
volume of pyramid = (1/3)(564001 ft2)(481 ft) Multiply these together.
volume of pyramid ≈ 90 428 160 ft3
And 90 428 160 ≈ 9.0 * 107
