Question #173018

A cube made of lead measures 3 cm on each side and a mass of 310.50 grams. What is its density in g / cm3?

a. 10.35 g/cm3 b. 11.50 g/cm3 c. 34.5 g/cm3 d. 103.5 g/cm3

Expert's answer

The density is mass divided by volume:

"\\rho=\\frac mV=\\frac{m}{a^3}=\\frac{310.50}{3^3}=34.5\\text{ g\/cm}^3."
