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

We are given;

We are required to get the density of the cube;

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

i believe the answer is true.
