Question

A brick has a mass of 17.3 kg and a volume of 914 cm3.

Evaluate the density of the brick in g/cm3 rounded to 3 significant figures.

Answer 1

`d=18.92\ g/cm^3`

Explanation:

Given that,

The mass of a brick, m = 17.3 kg

Volume of the brick, V = 914 cm³

We need to find the density of the brick.

17.3 kg = 17300 g

Density is equal to mass per unit volume. So,

`d=(m)/(V)\\\\d=(17300\ g)/(914\ cm^3)\\\\d=18.92\ g/cm^3`

So, the density of the brick is
`18.92\ g/cm^3`.
