Suppose you were going to design a front door and doorway to fit snugly enough to keep out the drafts, yet to be easy to open. (You are not showing off precision carpentry here, but merely designing a convenient ordinary door by standard methods.) The dimensions are to be given in inches. To how many significant figures would you specify the length and width of the door and doorway?16 Assume a standard door is 30.000 by 81.0''.

Assume that on the surface of the Earth, g = 9.81 m/s² = 32.2 ft/s² (i.e., each to three significant figures). Make sure you are reporting the solution to the proper number of significant figures.
