Question

A cube of aluminum measures 3cm on each side and weighs 81 g. What is its density?

Please help me and tell me detailed steps on how to work it pleasee!​

Answer 1

3 g/cm^3

Step-by-step explanation:

Known information:

m (mass) = 81 g

v (volume) = 3cm×3cm×3cm = 27cm^3

Question: what is the density (ρ) = ...?

Answer:

ρ = m/v

ρ = 81 g / 27 cm^3

ρ = 3 g/cm^3

Hope it helps. Thanks!
