Arectangular block of lead measures 20.0 mm x 30.0 mm x 45.0 mm. if the only density of lead is 11.34 g/cm3, calculate the mass of the block.

The formula of density is:

 - (1)

Volume of the block =

Since,

So, volume of the block =

Density of the block = (given)

Substituting the values in formula 1:

Hence, the mass of the block is .

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
