Determine the dollar amount for the cement needed for a sidewalk that is 4 inches thick, 3 feet wide, and 40 feet long if the cement is $76 per cubic yard.
Answer provided by our tutors
The volume of the cement needed is the product of:
(4 inches)(3 feet)(40 feet)
=(4/36 feet)(3 feet)(40 feet)
=40/3 cubic yard
So the cost is 76*(40/3) = 1 013.33 dollars
