Suppose that you must order concrete for a sidewalk 35 ft by 4 ft to a depth of 5 in. How much concrete is required? Answer to the nearest $\frac { 1 } { 2 }$ cubic yard.
A) $2 \mathrm { yd } ^ { 3 }$
B) $58.5 \mathrm { yd } ^ { 3 }$
C) $26 \mathrm { yd } ^ { 3 }$
D) $2.5 \mathrm { yd } ^ { 3 }$
E) $700 \mathrm { yd } ^ { 3 }$

First, convert all measurements to feet: 5 inches is $ \frac{5}{12} $ feet. The volume in cubic feet is $ 35 \times 4 \times \frac{5}{12} = \frac{700}{12} \approx 58.33 $ cubic feet. Convert cubic feet to cubic yards by dividing by 27: $ \frac{58.33}{27} \approx 2.16 $ cubic yards, which rounds to $ 2.5 $ cubic yards.
