Question 174733
have a roof 3000sq feet with 16inch wood shingles (100sq feet equal 1ft)
how many shingles would I need?
the answer options are: 33; 34; 35; 36 
or is this even possible with the answer options?
------------
Assuming that each shingle is 16" x 16" 
the area of each is (4/3 ft.)^2 = (16/9) sq. ft.
------------------
# of tiles needed = 3000sq ft/(16/9)sq ft = 1687.5
===================================
Your answer options make no sense.
