## Task 3 - 010713

During a class day on socialist production, a student saws off a piece of square steel that weighs 475 p. The next day, a piece of square steel, whose dimensions are four times larger than those of the sawn-off piece and which is made of the same material, is processed.

How heavy is the piece? Justify your answer!
The volume increases proportionally with each dimension; since there are three possible dimensions, the new piece has a volume that is $4 \cdot 4 \cdot 4=64 \text{ times}$ larger. The weight behaves (with the same material) like the volume, so the new weight is 30400 p.
