# A Cube of 9 Cm Edge is Immersed Completely in a Rectangular Vessel Containing Water. If the Dimensions of the Base Are 15 Cm and 12 Cm, Find the Rise in Water Level in the Vessel. - Mathematics

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.

#### Solution

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
