Question

An object has a mass of 630 kg and a volume of 7 m cube.

Find the density of the object in kg/m cube.​

Answer 1

Explanation:

Hey there!

According to the question;

Mass of an object (m) = 630 kg

Volume of an object (v) = 7m³

We know that;

`density = \frac{mass(kg) \: }{volume( {m}^(3) )}`

or, density = (630/7) kg/m³

Therefore, density of the substance is 90kg/m².

Hope it helps!
