Question 1151990: A furniture builder is hired to build a bookcase. He begins by building the frame of the bookcase: top, bottom, and sides. The width is 2 meters, the height is 3 meters, and the depth is 0.5 meters. If the lumber cost on average $3 per square foot, what is the BEST estimate for the cost of the materials to build just the frame of the bookcase?

The 2 sides have an area:
+2%2A3%2A.5+=+3+ m2
The top and bottom add up to:
+2%2A2%2A.5+=+2+ m2
The total area adds up to:
+3+%2B+2+=+5+ m2
----------------------
The cost of these materials is:
+5%2A3+=+15+
$15
The best estimate may include some waste
after cutting boards to length, but that
waste is unknown.
