Volume of Pyramid is given by:
V=%281%2F3%29Bh
Where B = Base Area, and h = height
You are given V already, and you can figure out B, since the problem gives you the sides of the square base. The area of a square = s^2, which is 16cm^2 in this case. Substituting these values into the above equation gives you:
80=%2816%2F3%29h
h=%2880%2A3%29%2F16
highlight%28h=15%29
