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

146,610.00 kg

Step-by-step explanation:

The density of a substance is given by

`d=(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`
