Eight workers can build a cabin in 60 hours. How many workers are needed if the cabin is to be built in 32 hours?
Since we are given no information to the contrary, the following discussion assumes that all men are created equal, and every worker accomplishes the same amount of work in the same amount of time. Since 8 workers can build a cabin in 60 hours, the job comprises (8 man) times (60 hours) = 480 man-hours of labor. That doesn't change. Now however, 480 man-hours of labor must be completed in 32 hours. The number of workers required to accomplish this is (480 man-hours) divided by (32 hours) = 15 man.

How many trees does it take to build a building?
How many trees it takes to build a house depends on the size, style and finish of the house. It varies considerably. According to the Idaho Forest Products Commission, a typical 2000 square foot house requires 26,700 board feet. An "average" tree with a 20 inch diameter and 42 linear feet of usable wood generates approximately 260 board feet. Doing the math indicates about 102 trees for that house. Other organizations in the lumber industry state different numbers, some as low as 30 trees for a 1500 square foot house while some state 60 trees for a 2000 square foot house.
