He will dig a hole that is 40.0 feet wide by 80.0 feet long and 7.5 feet deep. He first uses his shovel and scoops up 1.00 kg of dirt, and then determines that the dirt has a volume of 600 cm3. The excavator knows that his dump truck can only carry 8,000 kg of dirt. How many dump-truck loads will it take to haul the dirt away?
(1 in = 2.54 cm) ________ dump-truck loads
2. What will be the cost of gasoline for a 1320-mile trip from Wytheville to Orlando in a car that gets 28.0 miles per gallon, if the average price of gas is $3.25 per gallon? $________
3. The density of silver is 10.5 g/cm3. Express this density in pounds per cubic inch. ft3 (1 in = 2.54 cm) (2.20 lb = 1 kg) ___lb/in3
