Here is a start. Find volume, then new height.

12^3 = Volume = 12 * (12+4) * h

Original box = 12^2 * 5 = material.

New box = 12(12+4) + 2(12h) + 2(12+4)h = material

• math -

a volume is 864 what is the length width and height if length and width are the same and height is half of width and length
