Trim and Baseboard worksheet

1. 15 ft pieces to buy: 5

1. Add up the 5 wall lengths to get the total run the trim must cover

   $18+15+12+9+5$$=59\text{\hspace{0.17em}ft}$

2. Subtract the door openings, because baseboard stops at each one

   $59-1\times 3$$=56\text{\hspace{0.17em}ft}$

3. Add 12% extra, because corner cuts and short leftovers use up trim

   $56\times 1.12$$=62.72\text{\hspace{0.17em}ft}$

4. Divide by 15 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{62.72}{15}$$=4.1813$$=\text{rounded up:}5$

2. 22 ft pieces to buy: 2

1. A rectangle has two walls of each size, so add the length and width and double it

   $2\times \left(12+8\right)$$=40\text{\hspace{0.17em}ft}$

2. Subtract the door openings, because baseboard stops at each one

   $40-2\times 3$$=34\text{\hspace{0.17em}ft}$

3. Add 9% extra, because corner cuts and short leftovers use up trim

   $34\times 1.09$$=37.06\text{\hspace{0.17em}ft}$

4. Divide by 22 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{37.06}{22}$$=1.6845$$=\text{rounded up:}2$

3. 12 ft pieces to buy: 6

1. A rectangle has two walls of each size, so add the length and width and double it

   $2\times \left(18+13\right)$$=62\text{\hspace{0.17em}ft}$

2. Add 10% extra, because corner cuts and short leftovers use up trim

   $62\times 1.1$$=68.2\text{\hspace{0.17em}ft}$

3. Divide by 12 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{68.2}{12}$$=5.6833$$=\text{rounded up:}6$

4. 13 ft pieces to buy: 4

1. A rectangle has two walls of each size, so add the length and width and double it

   $2\times \left(13+11\right)$$=48\text{\hspace{0.17em}ft}$

2. Add 8% extra, because corner cuts and short leftovers use up trim

   $48\times 1.08$$=51.84\text{\hspace{0.17em}ft}$

3. Divide by 13 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{51.84}{13}$$=3.9877$$=\text{rounded up:}4$

5. 14 ft pieces to buy: 6

1. A rectangle has two walls of each size, so add the length and width and double it

   $2\times \left(14+18\right)$$=64\text{\hspace{0.17em}ft}$

2. Add 11% extra, because corner cuts and short leftovers use up trim

   $64\times 1.11$$=71.04\text{\hspace{0.17em}ft}$

3. Divide by 14 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{71.04}{14}$$=5.0743$$=\text{rounded up:}6$

6. 10 ft pieces to buy: 7

1. Add up the 5 wall lengths to get the total run the trim must cover

   $14+12+14+12+6$$=58\text{\hspace{0.17em}ft}$

2. Add 11% extra, because corner cuts and short leftovers use up trim

   $58\times 1.11$$=64.38\text{\hspace{0.17em}ft}$

3. Divide by 10 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{64.38}{10}$$=6.438$$=\text{rounded up:}7$

7. 16 ft pieces to buy: 4

1. Add up the 5 wall lengths to get the total run the trim must cover

   $13+12+10+12+7$$=54\text{\hspace{0.17em}ft}$

   $54\times 1.12$$=60.48\text{\hspace{0.17em}ft}$

3. Divide by 16 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{60.48}{16}$$=3.78$$=\text{rounded up:}4$

8. 16 ft pieces to buy: 4

2. Add 9% extra, because corner cuts and short leftovers use up trim

   $52\times 1.09$$=56.68\text{\hspace{0.17em}ft}$

3. Divide by 16 ft per piece, then round up, since trim is sold in whole pieces

   $\frac{56.68}{16}$$=3.5425$$=\text{rounded up:}4$

9. 15 ft pieces to buy: 4

1. Add up the 5 wall lengths to get the total run the trim must cover

   $14+12+14+12+6$$=58\text{\hspace{0.17em}ft}$

2. Subtract the door openings, because baseboard stops at each one

   $58-1\times 3$$=55\text{\hspace{0.17em}ft}$

3. Add 9% extra, because corner cuts and short leftovers use up trim

   $55\times 1.09$$=59.95\text{\hspace{0.17em}ft}$
