CONVERTING ALL MEASUREMENTS TO INCHES WE HAVE:
1-9=21
2-3=27
3-6=42
NOW WE'LL NEED 2 PIECES OF ALL COMBINATIONS OF SIDES THUS
2(21*27)+2(21*42)+2(27*42)
2*567+2*882+2*1134
1134+1764+2268
5166 SQUARE INCHES.
DIVIDING THIS FIGURE BY 144 (NUMBER OF SQUARE INCHES IN A SQUARE FOOT) WE GET:
5166/144=35.875 SQUARE FEET OF WOOD.
IF YOU WOULD RATHER WORK IN DECIMALS THEN:
1-9=1.75
2-3=2.25
3-6=3.5
2(1.75*2.25)+2(1.75*3.5)+2(2.25*3.5) ETC.
