Silver with a volume of 50 cm3 has a mass of 525 kg. What is the mass of silver with a volume of 30 cm3?

First, let’s find out what is the mass of 1 cm ^ 3 silver.

In the initial data for this task, it is reported that silver with a volume of 50 cm ^ 3 has a mass of 525 kg.

Since the mass of 1 cm ^ 3 of silver is 50 times less than the mass of silver with a volume of 50 cm ^ 3, the mass of 1 cm ^ 3 of silver is 525/50 = 21/2 = 10.5 kg.

Let’s find out what is the mass of 30 cm ^ 3 silver.

Since the mass of 30 cm ^ 3 silver is 30 times greater than the mass of 1 cm ^ 3 silver, then the mass of 30 cm ^ 3 silver is 30 * 10.5 = 315 kg.

Answer: The mass of 30 cm ^ 3 silver is 315 kg.
