Question

A rectangular block of 1m by 0.6m by 0.4m floats in water with 1/5th of its volume being out of water. Find the weight of the block.

Answer 1

Answer:

Weight of block is 191.424 Kg

Explanation:

The volume of rectangular block = $1*0.6*0.4 = 0.24$ cubic meter

1/5th of its volume being out of water which means water of volume nearly 4/5 th of the volume of rectangular block is replaced

Volume of replaced water = $\frac{4}{5} * 0.24 = 0.192$ cubic meter

Weight of replaced water = weight of rectangular block = $0.192 * 997$ Kg/M3

= 191.424 Kg
