Answer:

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.
