Question

Calculate the volume of 1280 kilograms of aluminium if the density of aluminium is 2700 kg/m³. Give your answer to 2 decimal places.

Answer 1

volume = 0.47
`m^(3)`.

Step-by-step explanation:

Density:

`d = (m)/(v)`

We have that d = 2700 kg/
`m^(3)` and that we have 1280 kg of Al.

`2700 = (1280)/(V)`

V = 0.47
`m^(3)`

Answer 2

The correct answer is 0.47 m³

Step-by-step explanation:

The formula for density (d) is

Mass (m) ÷ volume (v)

Hence

d = m ÷ v

The density of aluminium (as provided in the question) is 2700 kg/m³ and the mass of aluminium is 1280 kg, the volume is however unknown.

Thus, from the formula earlier

2700 = 1280 ÷ v

v = 1280 ÷ 2700

v = 0.47 m³

The volume of aluminium when the density is 2700 kg/m³ and the mass is 1280 kg is 0.47 m³
