Question

A cube of aluminum measures 3 cm on each side and weighs 81 g. What is its density? (HINT: find the volume of the block first)DMV

Answer 1

We have the following:

`d=(m)/(v)`

now,

`\begin{gathered} v=l^3 \\ v=3^3 \\ v=27 \end{gathered}`

The volume is 27 cm^3. replacing:

`\begin{gathered} d=(81)/(27) \\ d=3 \end{gathered}`

The density is equals a 3 g/cm^3
