Sawing a 2-meter-long cuboid wood into three sections will increase its surface area by 16 square meters. How many cubic meters is the original volume of this wood?


The surface area is increased by four bottom surfaces, that is, the area of each bottom surface is 16 / 4 = 4 square meters, so the volume is equal to 4 * 2 = 8 cubic meters
