A 5cm by 5cm by 4cm block is built from one hundred 1cm x 1cm x 1cm vubes, each of which is coloured red or white. Te cubes are arranged in such way that no two cubes touch along a face are the same colour. What is the number of red faces in the interor of the block and why?

It is suprising fact that 1 x 2 x 3 x 4 x 5 x 6 = 8 x 9 x 10. It is even more suprising that 8 x 9 x10 x 11 x12 x 13 x 14 is equal to another such product of consecutive whole numbers. What is the smallest number in this other product and why?
