Question

Concrete has a density of 2400 kg/m³. Calculate the mass of 150 m³ of concrete in kilograms.

Answer 1

The mass of the concrete is 360000 kg.

Explanation:

Given that,

Density of concrete, $d=2400\ kg/m^3$

Volume of concrete, $V=150\ m^3$

Let m is the mas of concrete. We know that the density of an material is equal to the mass per unit volume. Its expression is given by :

$d=\dfrac{m}{V}$

$m=d\times V$

$m=2400\ kg/m^3\times 150\ m^3$

m = 360000 kg

So, the mass of the concrete is 360000 kg. Hence, this is the required solution.
