I need help with this problem

  1. Sep 16, 2003 #1
    Please, can you help me I need to help to find density for solid cube and cylinders ex.wood cube,wood cylinders, aluminum cube. I need to find density without the volume. I looking for the equation to work out the problems.

    I can't use D=mass/volume

    I have no volume to calculate
    because we only measure the length, width and mass
    in our physics lab class.


    Thank you

    Rectangular prism-
    Density= mass/(length*width*height)

    Cube-
    Density= mass/width cubed

    Cylinder
    Density= mass/(pi*radius squared*height)

    Or do those not count??

    Thank-You

    Thank-you Gale 17, I can use these equations they do count.

    Incidentally, the formulae Gale listed are density = mass / volume.
