"The strength of a cable is proportional to the square of its diameter."
A 2-cm cable has a diameter of 2 cm, and a 3-cm cable has a diameter of 3 cm.
If a 2-cm cable supports 800kg, so a 3-cm cable supports:
800*(3/2)²
=?
The strength of a cable is proportional to the square of its diameter. If a 2-cm cable will support 800kg, how much will a 3-cm cable support?
