Suppose the grains of rice are cubes so that you could pack them in with no space between them. Divide 144 400 000 000 mm^{3} by a trillion to see how large your "cubic grain of rice" can be. This size calculation will be in cubic millimetres so take the cube root to find the side length of your "cubic grain of rice". How does this compare to an actual grain of rice? Penny
