Question

the mass of a cube using the triple beam balance is 21g. the volume of the cube is 7cm cubed. what is the density of the cube? show step by step please

Answer 1

3g/cm3

Step-by-step explanation:

The density equation is M over V so you divide the mass by the volume. You do 21 divided by 7 and you get 3

Answer 2

3 g/cm³

Step-by-step explanation:

The density of a substance can be found by using the formula

`density = (mass)/(volume) \\`

From the question

mass = 21 g

volume = 7 cm³

We have

`density = (21)/(7) = 3 \\`

We have the final answer as

3 g/cm³

Hope this helps you
