Answer:
3.5 cubic yards of cement we need.
Step-by-step explanation:
Given : You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 inches.
To find : How much cement is needed, in cubic feet? How many cubic yards of cement do you need?
Solution :
The length of the side walk is 95 feet long.
The width of the side walk is 3 feet long.
The depth of the concrete is 4 inches.
Convert inches into feet,
1 inch = 0.083 feet
