Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
You multiply its density by its volume.
The volume of a rectangular solid with those dimensions is 27 cm3.If we also knew its mass, then we could calculate its density.
The formula used to calculate the volume of a rectangular solid is: L*W*H=V
It is the point where the principal diagonals meet.
Volume= Length X Width X Height
You multiply its density by its volume.
The volume of a rectangular solid with those dimensions is 27 cm3.If we also knew its mass, then we could calculate its density.
If this rectangular solid is actually in your possession, then you would measure it and calculate the volume, after which you can derive the density by dividing the mass by the volume. If it is not in your possession, then you are clearly being asked to call upon your psychic powers to solve this problem.

on a balance
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
just multiply length by height by depth/width.
Volume= Length X Width X Height
Density = Mass / Volume. There is not an instrument that will measure both so you will need to measure them separately and calculate the density.
Density = Mass/Volume so Volume = Mass/Density. Provided the object is solid.
