Asquare pyramid has a height h and a base with side length b. the side lengths of the base increase by 50%. write a simplified expression that represents the volume of the new pyramid in terms of b and h.

The general formula for the volume of a square pyramid is

V = (1/3)b^2 h

If b increase by 50% their new length = 3b/2

Therefore the volume of the new pyramid is

V = (1/3) (3b/2)^2 h

  = (1/3)  9b^2 / 4   h

  =  3/4b^2 h Answer
