The surface area of a cube is given by:



Where is the measure of one of the edges. So:



Solve for a numerical approximation of . Note the instruction to express your answer to an inappropriately precise 2 decimal places. You need to follow the instruction despite the fact that the proper representation of the measure of a side of this cube is to the nearest whole inch because the surface area was given to the nearest whole square inch. No result of a calculation involving measurements should be expressed with greater precision than the least precise of the input measurements.
