A new sidewalk will be 6 feet wide, 260 feet long, and filled to a depth of 9 inches (0.75 foot) with concrete. How many cubic yards of concrete are needed?

43.29 yard³

Step-by-step explanation:

Given that:

Width = 6 feets

Length = 260 feets

Depth =. 0.75 foot

Volume = length * width * depth

Volume = 6 * 260 * 0.75

Volume = 1,170 feet³

Converting 1170 feet³ to yard³

1 cubic feet = 0.037 cubic yard

Hence,

1,170 feet³ = ( 0.037 * 1170) = 43.29 yard³

Hence, 43.29 yard³ of concrete are needed.
