Question

a pyramid has a square base with sides of length s the height of the pyramid is equal to 1/2 of the length of a side on the base which formula represents the volume of the pyramid

Answer 1

V=1/3Bh is the formula for the volume of a pyramid.
B=2s (since the area of a square is A=Bh)
h=1/2s
The formula, when B and h are plugged in, is V=1/3(2s)(1/2s). This is not simplified.
Hope it helps!
