His weight doesn't depend on the area of his contact with the scale.
If it did, then we would see differences in our weight when we wear tennis shoes,
fancy shoes, snow boots, socks, and flip-flops. What really happens is that any
difference we see is only the difference in the weight of whatever we're wearing on
