I need to find the dimensions of this rectangular prism. It has a volume of 108 cubic inches. The length and width of the base are identical. The height is half of the length. Can you help explain how to do this given this information?

V = L * H * W

L = W = 2H

V = 2H * H * 2H

Insert values and solve for H, then L and W.
