Question

A pyramid shaped building is 873 ft tall with a square base that is 147 ft on each side. What is the volume of the​ pyramid?

Answer 1

Answer:

$V=6.28\times 10^6\ cm^3$

Step-by-step explanation:

We have,

Height of pyramid shaped building, h = 873 ft

This pyramid consists of a square base that is 147 ft on each side.

It is required to find the volume of the​ pyramid. When the base of pyramid is square, its volume is given by :

$V=\dfrac{1}{3}Bh$

B is area of base, $B=147\times 147=21609\ ft^2$

i.e.

$V=\dfrac{1}{3}\times 21609\times 873\\\\V=6288219\ ft^3$

or

$V=6.28\times 10^6\ cm^3$

So, the volume of the pyramid is $6.28\times 10^6\ cm^3$.
