A block of material (labeled A in the diagram) with a width w

C1 DENSITY

C1-RTO1: CUTTING UP A BLOCK-DENSITY

A block of material (labeled A in the diagram) with a width w, height h and thickness t has a mass of M_{+}distributed uniformly throughout its volume. The block is then cut into three places, B, C. and D. as shown.
