The volume of a pyramid with a square base is 99 mm3 and the height is 9.5 mm. What is the length of each side of the base?

The formula for the volume of a square pyramid is V=Bh

Plug in the numbers you are given: 99=B (9.5)

Divide (9.5) from both sides: 99/9.5 = B

You get approximately 10.42105

B = s*s = s^2

So, 10.43=s^2

sqrt 10.43=s

S = approx. 3.22
