Answer

Answer key: Siding worksheet

1. Siding needed (with waste): 15.3 squares
1. Find the wall area: the distance around the house times the wall height
  $2 \times (36 + 34) \times 10$ $= 1,400 ft²$
2. Add the gables. Each one is a triangle, so its area is half the base times the height
  $2 \times 0.5 \times 24 \times 4$ $= 96 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $1,400 + 96 - 2 \times 4 \times 8 - 9 \times 2 \times 3$ $= 1,378 ft²$
4. Add 11% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{1,378 \times 1.11}{100}$ $= 15.2958 squares$
5. Divide by 2 squares per box, and round up since you can't buy part of a box
  $\frac{15.2958}{2}$ $= 7.6479$ $= rounded up: 8$
2. Siding needed (with waste): 22.12 squares
1. Find the wall area: the distance around the house times the wall height
  $2 \times (55 + 35) \times 11$ $= 1,980 ft²$
2. Add the gables. Each one is a triangle, so its area is half the base times the height
  $2 \times 0.5 \times 37 \times 5$ $= 185 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $1,980 + 185 - 2 \times 4 \times 7 - 10 \times 2 \times 4$ $= 2,029 ft²$
4. Add 9% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{2,029 \times 1.09}{100}$ $= 22.1161 squares$
5. Divide by 2 squares per box, and round up since you can't buy part of a box
  $\frac{22.1161}{2}$ $= 11.0581$ $= rounded up: 12$
3. Siding needed (with waste): 15.16 squares

  $2 \times (38 + 28) \times 10$ $= 1,320 ft²$
2. Add the gables. Each one is a triangle, so its area is half the base times the height
  $2 \times 0.5 \times 38 \times 6$ $= 228 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $1,320 + 228 - 2 \times 3 \times 6 - 9 \times 3 \times 4$ $= 1,404 ft²$
4. Add 8% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{1,404 \times 1.08}{100}$ $= 15.1632 squares$
5. Divide by 2 squares per box, and round up since you can't buy part of a box
  $\frac{15.1632}{2}$ $= 7.5816$ $= rounded up: 8$
4. Siding needed (with waste): 10.68 squares
1. Find the wall area: the distance around the house times the wall height
  $2 \times (38 + 30) \times 7$ $= 952 ft²$
2. Add the gables. Each one is a triangle, so its area is half the base times the height
  $2 \times 0.5 \times 33 \times 5$ $= 165 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $952 + 165 - 2 \times 4 \times 7 - 10 \times 3 \times 3$ $= 971 ft²$
4. Add 10% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{971 \times 1.1}{100}$ $= 10.681 squares$
5. Divide by 1 squares per box, and round up since you can't buy part of a box
  $\frac{10.681}{1}$ $= 10.681$ $= rounded up: 11$
5. Siding needed (with waste): 15.37 squares
1. Find the wall area: the distance around the house times the wall height
  $2 \times (50 + 34) \times 9$ $= 1,512 ft²$
2. Add the gables. Each one is a triangle, so its area is half the base times the height
  $1 \times 0.5 \times 24 \times 7$ $= 84 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $1,512 + 84 - 2 \times 3 \times 7 - 12 \times 3 \times 4$ $= 1,410 ft²$
4. Add 9% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{1,410 \times 1.09}{100}$ $= 15.369 squares$
5. Divide by 2 squares per box, and round up since you can't buy part of a box
  $\frac{15.369}{2}$ $= 7.6845$ $= rounded up: 8$
6. Siding needed (with waste): 15.52 squares

  $2 \times (45 + 22) \times 10$ $= 1,340 ft²$
2. Add the gables. Each one is a triangle, so its area is half the base times the height
  $2 \times 0.5 \times 38 \times 7$ $= 266 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $1,340 + 266 - 3 \times 3 \times 7 - 11 \times 3 \times 4$ $= 1,411 ft²$
4. Add 10% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{1,411 \times 1.1}{100}$ $= 15.521 squares$
5. Divide by 2 squares per box, and round up since you can't buy part of a box
  $\frac{15.521}{2}$ $= 7.7605$ $= rounded up: 8$

  $1 \times 0.5 \times 34 \times 8$ $= 136 ft²$
3. Add the walls and gables, then take away the doors and windows you won't cover
  $1,700 + 136 - 2 \times 3 \times 6 - 10 \times 2 \times 4$ $= 1,720 ft²$
4. Add 10% for waste, then divide by 100 because each square covers 100 ft²
  $\frac{1,720 \times 1.1}{100}$ $= 18.92 squares$
