1100 = s^2*15 where s is the sides of the base (it's a square, so it has 4 equal sides)
1100/15 = s^2
73.333 = s^2 NOTE: 73.333 is the square of the side of the base, meaning that 73.333 is the area of the base.
Now take the square root, both sides:
s = 8.563 This is the length of each side
8.563*4 = 25 is the perimeter of the base.

A square based pyramid has a volume of 1100 mm^3. It's height is 15 mm. Calculate the dimensions of the base of the pyramid.

Volume of a rectangular pyramid: , where G is the AREA of the BASE, and h is the height
Since this is a square-based pyramid, and with S being a side of the base, the AREA of BASE, = .
We then get: Volume = . Computed, a side of the square base is:
