Question

A piece of granite with a volume of 40 cm^3 has a mass of 108g. What is the mass of a piece of granite the volume of which is greater by 35 cm^3?

Answer 1

The mass of the piece of granite with volume of 75 cm^3 is 202.5 grams.

Explanation:

Let

m = the mass of a piece of granite whose volume is: 40 + 35 = 75 cm^3 (greater by 35 cm^3)

Since Density = Mass / Volume and we are talking about pieces of the same material (same density) we can write:

m/75 = 108/40

m = 202.5 g
