The formula for the density of an object is d = my, where m is the mass and V is the volume. Solve the formula for m in terms of d and V.

m = dV

Step-by-step explanation:

A really helpful set of triangles I learnt were ones pertaining to this. They are called triangles, and in your case, the density mass volume triangle would be very helpful.

Simply, you cover the value that you want to get and depending on where the other two are located, you either multiply or divide the two.

To solve the formula in terms of m (m= dV) look at the triangle and cover the mass part, now you know what to do because the bottom two are exposed and these are multiplied together, so the formula is:

m = dV

Hope this helps!
