So to find the volume of a square pyramid, the formula is 1/3B2h or Base squared times height divided by 3 because of the triangular pyramid. So the base is 11, the height is 15 so 11 squared is 121 and the height is 15, so 121 times 15.
121 x 15= 1,815.
Now we divide by 3 because of the formula, so 1,815 divided by 3 is...
1,815 / 3= 605 cm squared!
