Question

A cube has a mass of 42 grams and a volume of 15 cubic centimeters. What is it’s density?

Answer 1

Answer:

2.8g/cm³

Explanation:

Given parameters:

Mass of cube = 42g

Volume of cube  = 15cm³

Unknown:

Density of the cube  = ?

Solution:

Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:

 Density  = $\frac{mass}{volume}$  

So;

 Density  = $\frac{42}{15}$   = 2.8g/cm³
