To find the volume of these 8 cubes you will use the surface are that is given to find the length of one edge.
If the surface area if 96 square cm, that means each side measures 16 square cm (96/6) because there are 6 congruent faces.
These means the side length(each edge) is 4 cm long. Use this to find the volume and multiply by 8.
V = lwh
4 x 4 x 4 x 8
V = 512 cubic cm
The total volume is 32768 cubic centimeters.
