Question #2b390

Answer 1

See below.

Explanation:

Density is mass divided by volume. You have not given any units in your question.

It is normally given as:

`(kg)/m^3`

but can be scaled up or down.

If we take the units to be grams and cubic centimetres.

Then:

`(54g)/(40cm^3)`

Dividing top and bottom by `40` gives:

`(1.35g)/(cm^3)` this can also be written `1.35g` `cm^-1`

So this would be read as 1.35 grams per cubic centimetre.
