A plan for a bookcase requires three pieces of lumber 3 ft 5 in each long and two pieces of lumber 2 ft 4 in each long. What is the total length of material that is needed for the bookcase?

3ft * 3 = 9 feet
5 inches * 3 = 15 inches
So the three pieces of lumber equal 9 feet and 24 inches = 11 feet
Add the two pieces to 11 feet.

2ft* 2= 4ft
4in*2= 8in

so it would be 11ft + 4ft 8 in?
