If a cube has an edge long L then the sum of all the edges is 12L, because there are 12 edges. Thus, in our case, an edge is 3 inches, and the volume is 3 to the 3,that is 27.

To form a cuboid we need 12 sides. Total, we are having 36 inch long wire.....so, for 12 sides we can get 3 inch each from that wire clearly. Thus, volume of cube with side 3 is (3)^3 i.e. 27
