Problema Solution
A new sidewalk will be 5 feet wide, 100 feet long, and filled to a depth of 6 inches (0.5foot) with concrete. How many cubic yards you of concrete are needed?
Answer provided by our tutors
1 yd = 3 ft
1 yd^3 = 9 ft^3
1 ft^3 = 1/9 yd^3
The volume of the concrete in ft^3 is:
V = 5*100*0.5
V = 250 ft^3
V = 250*(1/9) yd^3
V = 27.78 yd^3
27.78 cubic yards of concrete are needed.
