How do I find mass from density and weight?

Question

An ice block has a density of 917 kg/m3 and a weight of 2000 kg

how do i find the volume of it?

Answer 1

Mass of the ice block,m=2000 kg

Density ,Rho=917 kg/m^3

Using density formula

Rho=Mass/Volume

Volume,V=m/Rho

                 = 2000/917

               =2.181 m^3

                 

Answer 2

Mass or weight of an ice block = 2000kg.

Density of an ice block = 917 kg/m³.

Volume is defined as mass per unit density.

Volume = mass / density

            = 2000 kg / 917kg/m³

            = 2000 m³/ 917

            = 2.1810 m³

Therefore volume of an ice block is 2.181 m³.
