Question

The great pyramid has a height of about 480.7 feet and base edges about 756 feet. The base is almost square. Find the approximate volume of this pyramid.
A) 571,530 ft

B) 90,000,000 ft

C) 91,579,118.4 ft

D) 274,737,355.2 ft

Is it A, B, C, or D?

Answer 1

The answer to this question is C

Answer 2

Given, a pyramid with height = 480.7 ft

The base is a square and the length of the side = 756 ft.

We know that the formula to find the volume is

$V = a^2\frac{h}{3}$

Here, h = 480.7 ft and a = 756 ft.

By substituting the values of a and h in the formula we will get,

$V = (756)^2(\frac{480.7}{3} )$

$V = (571536)(\frac{480.7}{3} )$

$V= \frac{(571536)(480.7)}{3}$

$V= \frac{274737355.2}{3}$

$V = 91579118.4$

So we have got the required answer.

The volume of the pyramid = $91579118.4 ft^3$.

So option C is correct here.
