I'm trying to find the height of the rectangular pyramid
The general formula for the volume of a pyramid is:

Area of the base * Height * 1/3
The volume of a pyramid with a rectangular base is equal to:

Length_of_base * Width_of_base * Height * 1/3

1125 = 18 * 15 * h * 1/3

1125 = 90h

1126/90 = h

12.5111 = h
