The volume of a rectangular solid is to be increased by 50% without altering itsbase. To what extent the height of the solid must be changed.

The volume of a rectangular solid is to be increased by 50% without altering itsbase. To what extent the height of the solid must be changed. Correct Answer 50%

Let l, b the sides of the base, so that the area of the base = lbremains constant.Let ‘h’ be the height of the solid.Volume of the solid, V = l× b× h.Since the volume is to be increased by 50%
