Question
If the length, breadth and height of a box of cuboid
shape is increased by 10%, 25% and 40% respectively, then what would be the percentage change in the volume of the box?Solution
Percentage change of length and breadth = 10 + 25 + `(10 xx 25)/(100)` Â = 35 + 2.5 = 37.5% Percentage change of breadth and height = Â 40 + 37.5 + `(40 xx 37.5)/(100)` Â = 77.5 + 15 = 92.5%
