above. Note that two pieces, each 4' - 6" long, are

required. To develop columns 6 and 7 which relate

to each other, try a 10-foot length.

Converting to inches:

In this example, column 4 is omitted since it

10' - 0" = 10 x 12 = 120 inches

is not used in the calculations.

4' - 6" = (4 x 12) + 6 = 48 +

Then:

6 = 54 inches

above), observe that the item requires two pieces,

each 3' - 0" long. In selecting the standard length

(column 6) and the number per standard length

(column 7), calculate on the closest standard length

by trying an 8-foot versus a 10-foot length.

Converting to inches:

= 2 pieces w/12 inches waste

8' - 0" = 8 x 12 = 96 inches

3' - 0" = 3 x 12 = 36 inches

Trying a 12-foot standard length:

Then:

12' - 0" = 12 x 12 = 144 inches

4' - 6" = (4 x 12) + 6 = 48 +

6 = 54 inches

= 2 pieces w/24 inches waste
