Question

a cube of side 8 centimetre is immersed completely in a rectangular vessel containing water. if the length and the breadth of the base of the whistle are 16 cm and 12 centimetre respectively, find the rise of water level in the vessel ​

Answer 1

Step-by-step explanation:

Given, edge of the cube = 11 cm

Dimension of the base of the rectangular vessel = 15 cm × 12 cm

Let the rise in water level in the rectangular vessel be h cm.

Since, the cube is completely un messed in the rectangular vessel,

∴ Volume of water displaced in the rectangular vessel = Volume of the cube

⇒ 15 cm × 12 cm × h = (11 cm)3

⇒ h ≈ 7.39 cm

Thus, the rise in water level in the rectangular vessel is 7.39 cm approximately.
