# I need help with this problem

#### prokoro

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

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.
