The surface area of a cuboid is 56 square centimeters, which can be divided into three equal cuboids. What is the volume of this cuboid?
The cuboid can be divided into three equal cubes, which shows that the cuboid is equal in width and height, and its length is three times of its width
If the width is x, the height is x and the length is 3x
2(3x*x+x*x+3x*x)=56
14x^2=56
x=2
3x=6
V = 2 * 2 * 6 = 24 (cm3)
