Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

We know the density and weight of the cube, we need to know the length. How do I figure this one out?

volume = weight/density

volume = (side)^3

or side = (volume)^(1/3)

Be sure you know what cubic units are used to express the density, the side of the cube will be given in that linear unit.

example, 100 kg of water, 1 kg/L. You can't use liter, but 1 liter = 1 dm^3

(100 dm^3)^(1/3) = 4.64 dm or 464 mm.

Similarly, in "english" units if you have gallons, you'd have to convert to cubic inches or cubic feet.
