Answer:

#E=DVc^2#

Explanation:

Both equations have one thing in common: #m#. You're going to want to rearrange one of them to make #m# the subject, and then substitute this into the other equation.

For example,

#D=m/V#

multiply both sides by #V# and you get

#DV=m#.

Since these two are equivalent, you can insert this into #E=mc^2#, like so

#E=mc^2#
#E=DVc^2#

since #c^2# is just a constant, you can now find energy given density and volume.
