Question

A cube of 9 cm edge is immersed completely in a rectangular vessel containing water. Ifthe dimensions of the base are 15 cm and 12 cm, find the rise in water level in the vessel.

Answer 1

Volume of cube `=S^3=9^3=729cm^3`

Area of base `lxxbxx15xx12=180cm^2`

Rise in water level = `"Volume of cube"/"Area of base of rectangular vessel"`

`(729)/180=4.05cm`
