Question

A cube measures 2.5 cm in height and has a density of 3.0 g/cm³. What is the mass?

Answer 1

Answer: mass: 46.875 g

Explanation:

$density = \frac{mass}{volume}$

density = 3.0 g/cm^3

volume (lwh are all 2.5 since it is a cube) = 2.5^3 = 15.625

mass = ?

$3 = \frac{mass}{15.625}$

mass = 3*15.625 = 46.875
