1. A cube has a mass of 40 grams. One side of the cube has a length of 3.4. What is the Density of the cube?

1.0177 g/cm³

Explanation:

We are given;

Mass of the cube = 40 grams Length of the cube = 3.4 units

We are required to get the density of the cube;

Assuming the length is 3.4 cm The volume of the cube is given by l³

Thus, Volume of the cube = 3.4 cm * 3.4 cm * 3.4 cm

= 39.304 cm³

But, density = Mass : volume

= 40 g : 39.304 cm³

= 1.0177 g/cm³

Therefore, the density of the cube is 1.0177 g/cm³
