    Re: Chemistry

    How should you find the volume of that rectangular block? You do know how to calculate the volume of a cube or rectangular box, right?

    And density is just mass per volume. So once you have the volume in cubic cm, you can calculate the density in grams per cubic cm. Give it a go and show your work (and keep showing the units in your calculations to help keep things straight)...
