Q How many 2X6 pieces of 16 ft x 5 1/2 ins. for a porch that measures 16ft x 14ft?

I changed the mixed number to an improper fraction (11/2) and found the area (224).

11/2 x 224/1

**Reiny**, Monday, April 4, 2011 at 7:57pmSince your porch is 16 ft long and each of the 2by6's is also 16 feet long, all you have to care about is how many are neeedd side by side to go 14 feet

14 feet = 168 inches

so number of pieces to fit sideways = 168/5.5 = 30.5

Problem I see, ..

Usually a space is left between adjoining pieces of lumber , you do not say how much that space is.

The above solution implies that we leave no space, which is not advisable.

Anyway, according to the above math, you would need 31 pieces, having to cut the last piece.
