14. Calculate the number of squares of 1” × 8” drop siding
(to the nearest square) required for a hip roof structure
that is 50' long and 20' wide with 10' high walls, fifteen 3'
× 5' windows, one 8' × 7' garage door, and two 8' × 7'
sliding doors (Assume a 16% waste allowance, hint: 1
square = 100 square feet) (Page 4.20, 21 - Section 5.1.0).
Answer
(2(50’ X 10’) + 2(20’X10’))-(15(3’X5’)+(8’X7’)+2(8’X7’))
then take 16% of that answer and add to it for waste
allowance. Divide the answer by 100 square feet to
equal the number of squares needed.
Result: (1007 Sq. Ft. +161.12 Sq. Ft. waste
allowance)/100Sq. Ft. = 11.6812 or 12 squares of siding.

windows, one 8' × 7' garage door, and two 8' × 7' sliding
doors (Page 4.20, 21 - Section 5.1.0 see note on page
4.20).
Answer
(2(50’ X 10’) + 2(20’X10’))-((8’X7’)+2(8’X7’)) take no
waste allowance. Divide the answer by 100 square
feet to equal the number of squares needed.
Result: (1232 Sq. Ft.)/32 Sq Ft. per panel = 38.5 or
39 4’ X 8’ panels
