The formula for the area of a rectangular prism is

V=l*w*h
In this case, the l=(3+3+3+3=12)12in, the w=(3+3+3+3=12)12in, and the height=(3+3+3+3+3=15)15in
plug in the data we know
V=12*12*15
V=144*15
V=2160in³

a cube has all the size equal,so if it 3 inches then the volume = 3x4= 12
then the 6 sides=12×6=72 inches
