I am failing math and I need help? Solve this equation:The city of Rubberville plans to dig a rectangular landfill. The landfill will have a base with dimensions 700 feet by 200 feet and a depth of 85 feet.A.)An excavator was hired to dig the hole for the landfill. How many cubic yards of dirt will he have to haul away?
Given dimensions of the landfill are - 700ft x 200ft x 85 ft Hence total volume to be excavated = 700ft x 200ft x 85 ft = 11,900 cub.ft = (11,900 divided by 27) cub.yd. = 440.740 cub.yd (Note that 27 cub.ft = 1 cub.yd)
l=700 feet=233.33yards b=200 feet=66.67yards h=85 feet=28.33yards Dirt removed = volume of the landfill. = l*b*h =233.33yards*66.67yards*28.33yards =440704.627463 cubic yard
