II  Cuboid volum.e  II  II  II  II  II  II




            You  know that a quick way to find the volume of any cuboid is like this:
            Volume = length x breadth x height   or   V = I x   x h.
            (You  might prefer to use the word 'width ' instead of 'breadth '.)


        QJ      Copy and complete this equation

                for this cuboid made of Centicubes.

                V = l x b x h
                  = ... cm x 2 cm x 3 cm
                  = ... cm3
        [I]     Write about these cuboids in the same way.
