Question
If the edge of the cube is increased by 50%, then find
the percentage increase in the volume of the cube.Solution
Let the edge of the cube be x unit
Volume of cube = x³ cubic unit
New edge = 1.5x unit
New volume = (1.5x)³ = 3.375x³ cubic unit
Increase in volume = 3.375x³ – x³ = 2.375x³ cubic unit
Percentage increase = (2.375x³ / x³) × 100 = 237.5%
