In the figures below the cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches high how much greater is the voume of the cube shaped box than the rectangular box

The cube’s sides measures 6 inches and the measurement for the rectangular box is that it is 10 inches long, 4 inches thick and 4 inches high. To compute for the volume of a cube you must use the formula of V = a3 and for the rectangular prism is V = l x w x h.
Cube:    V = 6^3
              V = 216 inches^3
Rectangular Prism:       V = 10 x 4 x 4              
                                       V = 160 inches^3
To identify how much greater the volume the cube from the rectangular box we subtract their volumes.
N = C – R where N stands for the unknown C for the volume of cube and R for the volume of Rectangular Box
N = 216 inches^3 – 160 inches^3
N = 56 inches^3
So the cube is 56 inches3 greater than the rectangular box.

The answer would be choice b
