The volume of a rectangular solid is to be increased by 50% without altering its base. To what extent the height of the solid must be changed.
Correct Answer: 50%
Explanation:
Let l, b the sides of the base, so that the area of the base = lb
remains 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%
