What is the total measurement when adding 7'-4", 3'-6", 10'-10", 12'-5", and 9'-10" and then subtracting 69"?

To find the total measurement when adding the given lengths of wood and then subtracting 69 inches, we first need to convert all measurements to inches for easier addition and subtraction.

1. Convert each measurement from feet and inches to inches:

• 7'-4" = 7 x 12 + 4 = 84 + 4 = 88 inches

• 3'-6" = 3 x 12 + 6 = 36 + 6 = 42 inches

• 10'-10" = 10 x 12 + 10 = 120 + 10 = 130 inches

• 12'-5" = 12 x 12 + 5 = 144 + 5 = 149 inches

• 9'-10" = 9 x 12 + 10 = 108 + 10 = 118 inches

2. Now add these converted values together:

• Total = 88 + 42 + 130 + 149 + 118 = 527 inches

3. Next, we need to subtract 69 inches from this total:

• 527 - 69 = 458 inches

4. Finally, convert 458 inches back
