With any calculator, cubing is just repeated multiplication.

(7/6)^3, if you don't have an explicit raise-to-power feature for some reason, is just (7/6)*(7/6)*(7/6).

Holy thread necromancy, Batman!

For what I find to ne the simplest (but not necesarily most direct) calculations find the percentage of increase and cube that.

For example going from 6 to 7 ft is a 1,16 percent increase in height. so 1.16 x 1.16 x 1.16 equals 1.56 percent increase in weight. That would take you from 200 lbs to 312 lbs.

It is worth noting that a 12' humanoid will not follow the square/cube law exactly. Several factors don't scale directly. Skin thickness doesn't need to scale linearly. Bones increase above the cube of the scale factor, because strength is based upon cross section, and scales with mass supported. Circulatory systems need to scale Sq.Cu. above as well, due to greater pressure needed, which adds up quick. Teeth only need to scale to the square of the scaling factor, but in various species, falls between S and S, assuming no change in type of diet.
