a driveway is 162 feet long, 12 feet wide, and 6 inches deep. how may cubic yards of concrete will be required to lay the driveway? and pease explain answer
I goofed.
6 inches = O.5 feet = 0.167 yards
54 * 4 * 0.165 = 35.64 cubic yards
To determine the amount of concrete required to lay the driveway, we need to calculate the volume of the driveway first.
1. Convert the measurements to a consistent unit:
Since the depth is given in inches, we need to convert it to feet. There are 12 inches in a foot, so 6 inches is equal to 6/12 = 0.5 feet.
2. Calculate the volume of the driveway:
The formula for calculating the volume of a rectangular object is length × width × depth.
So, for the driveway:
Volume = 162 feet × 12 feet × 0.5 feet
3. Multiply the values:
Volume = 972 cubic feet
4. Convert the volume to cubic yards:
Since concrete is usually sold in cubic yards, we need to convert the volume from cubic feet to cubic yards. There are 27 cubic feet in a cubic yard (3 feet × 3 feet × 3 feet).
So, to convert cubic feet to cubic yards, we divide by 27:
Volume (in cubic yards) = 972 cubic feet ÷ 27
5. Calculate the final answer:
Volume (in cubic yards) = 36 cubic yards
Therefore, you will need 36 cubic yards of concrete to lay the driveway.
Change feet into yards.
162 feet = 54 yards
12 feet = 4 yards
0.5 feet = 1.5 yards
Multiply the three dimensions together.
54 * 4 * 1.5 = 324 cubic yards
