The mass of sand is 54 kg Calculate the mass of stones

To calculate the mass of stones, we first need to know the density of sand and stones. Let's assume the density of sand is 1500 kg/m^3 and the density of stones is 2500 kg/m^3.

Then we can calculate the volume of sand using the formula:
Volume = Mass / Density
Volume of sand = 54 kg / 1500 kg/m^3
Volume of sand = 0.036 m^3

Now, we can calculate the mass of stones using the formula:
Mass = Volume x Density
Mass of stones = 0.036 m^3 x 2500 kg/m^3
Mass of stones = 90 kg

Therefore, the mass of stones is 90 kg.
