Question

Calculate the mass (in kg) of 54.3 m³ of granite. The density of granite is 2700 kg/m³. Give your answer to 2 decimal places!!

Answer 1

Answer:

146,610.00 kg

Explanation:

The density of a substance is given by

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

where

m is the mass of the object

V is its volume

For the sample of granite in this problem, we know:

$V=54.3 m^3$ is the volume

$d=2700 kg/m^3$ is the density

So, we can re-arrange the equation to solve for m, the mass of the sample:

$m=dV=(2700)(54.3)=146,610.00 kg$
