Question #35835

Answer 1

`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.
