Question

a cube of 9 cm edge is immersed complety in a rectangular vessel containing water. if the dimensions of the base are15 cm and 12 cm find the rise in water level in the vessel
​

Answer 1

The rise edge of given cube = 9cm.

So, the volume will be 729cm^3

Let the rise in the water level be 'a' cm.

The volume of the cube = the volume of the water displaced by it.

• 15cm*12cm*a

• 729=15*12*a

• a=729/180

• a=4.05

The rise in the water level is 4.05cm.
