Yes.

Mass increases with the cube of scale, while structural material cross-section area increases only with the square of scale. So insects can have miniscule legs, while elephants have tree trunks, proportionally.

Right, sometimes called "square-cube law" (http://en.wikipedia.org/wiki/Square-cube_law). Worth knowing about so you can explain to yourself the differences noted above.
