A. how many boxes of screws are needed to install 66 sheets of 4-ft by 14-ft by 5/8-in gypsum board if it requires 1.2 screws nails per square foot and there are 500 screws per box? (5 pts) b. how many lug nuts are in the truck junkyard if there are 582 half-ton trucks and 1475 three- quarter-ton trucks? half-ton trucks have five lugs per wheel and three-quarter-ton trucks have six lugs per wheel. do not round number. (5 pts) c. convert 1 light-minute (the distance light travels in 1 minute) to chains (a surveying measurement). (6 pts) d. how many troy ounces are in a cube of steel whose sides are 1.5 meters long if steel has a density of 490 pounds per cubic foot? (7 pts) e. how many board feet (bdf) of lumber are in one hundred fir trees if each tree is 60-feet tall and 30 inches in diameter? assume a 30% waste factor for converting "trees" to slumber. the formula for board feet is (nominal width in inches x nominal thickness in inches x length in feet)/12.
