1. Determine the drywall, joint compound and tape needed to cover

four 8' high by 12' long walls. The drywall will be run horizontally and is

available in 4' widths and 12' lengths. To finish 100 ft2 of drywall, 0.4

boxes of joint compound and 0.13 rolls of tape are needed (1 box of

joint compound can cover approximately 250 ft² and a roll of tape can

cover the seams in a surface of approximately 770 ft2). Round your

answers up.
