## How many linear feet are in a 12×12 room?

Multiply the length times the width of the room to get the room square footage. 12 ft x 12 in/ft (width of the room) = 144 in. So the total linear footage of the 1 x 12 boards is found by multiplying 5 (boards) by 6 (feet) which equals 30 linear feet.

## How do I convert square feet to linear feet for roofing?
