A contractor pours a sidewalk that is 4 inches deep, 1 yard wide, and 20 yards long. How many cubic yards of concrete will be need? (Hint: 36 inches = 1 yard)
4 inches = 0.1111 yards
V = 0.1111 * 36 * 20
V = ?

To find the amount of concrete needed, you need to calculate the volume of the sidewalk in cubic yards.
First, convert the depth of the sidewalk from inches to yards:
4 inches ÷ 36 inches = 0.1111 yards (rounded to four decimal places)
Now, calculate the volume of the sidewalk by multiplying its width, length, and depth:
Volume = Width × Length × Depth
= 1 yard × 20 yards × 0.1111 yards
= 2.222 cubic yards (rounded to three decimal places)
Therefore, approximately 2.222 cubic yards of concrete will be needed.
