Question

What is the volume of a square pyramid with base side length of 22 cm and height of 8cm?

Answer 1

Answer is 1290.67. I rounded to the nearest tenth but it goes on.

Answer 2

Answer:

Volume of a pyramid is

$\frac{1}{3 } \times (area \: \: of \: base) \times height$

Since it's a square pyramid the base is a square

So we have

Area of a square = l²

where l is the length of one side

Area of square = 22²

= 484 cm²

So volume of the pyramid is

$= \frac{1}{3} \times 484 \times 8 = 1290.7 {cm}^{3}$

Hope this helps you
