Kilogram is weight, not volume.
The formula used to calculate the volume of a rectangular solid is: L*W*H=V
Volume= Length X Width X Height
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.
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
The answer depends on what part you want the volume for.

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.
It is length * breadth * height.
