Answer this question fast

the volume of a square pyramid with a height of 12 m is 100 m³. find the length of its square base.

5 m

Step-by-step explanation:

The volume (V) of a square based pyramid is

V = Ah ( A is the area of base and h the height ), thus

A × 12 = 100, that is

4A = 100 ( divide both sides by 4 )

A = 25

Hence s² = 25 ← s is the side of square base

Take the square root of both sides

s = = 5

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
