If each side of a cube is reduced by 20%, the volume of the cube will be reduced by?40%48.8%60%20%
Question
Solution 1
The volume of a cube is given by the formula V = s^3, where s is the length of a side.
If each side of the cube is reduced by 20%, the new side length is 0.8s.
The new volume V' is then (0.8s)^3 = 0.512s^3.
The reduction in volume is then V - V' = s^3 - 0.512s^3 = 0.488s^3.
