Question

A carver begins work on the following block of granite that weighs 2700 g. What is the density of the granite?

Answer 1

Given that,

Mass of the block, m = 2700 g

Let the dimensions of the block are 20 cm, 5 cm and 10 cm.

To find,

The density of the granite.

Solution,

Let d is the density of the granite. We know that the density of an object is equal to the mass per unit volume. So,

d = m/V

or

$d=\dfrac{2700\ g}{20\ cm\times 5\ cm\times 10\ cm}\\\\d=2.7\ g/cm^3$

So, the density of the block is 2.7 m/s².
