a new sidewalk will bee 6 feet wide 160 feet long and filled to a depth of inches 0.75 foot with concrete, How many cubic yards of concrete are needed
To calculate the cubic yards of concrete needed for the new sidewalk, we need to first convert all the measurements into the same unit. Let's start by converting the length and width to yards.
1 foot = 1/3 yard
So, the width of the sidewalk in yards would be:
5 ft * (1/3) = 5/3 yards
Next, let's convert the depth to yards.
1 inch = 1/36 yard
So, the depth of the sidewalk in yards would be:
3 in * (1/36) = 1/12 yard
Now we can calculate the volume of the sidewalk in cubic yards using the formula:
Volume = Length * Width * Depth
Volume = 160 ft * 5/3 yards * 1/12 yard
Volume = 160 * 5/3 * 1/12 cubic yards
Volume = 400/9 cubic yards
Therefore, approximately 44.44 cubic yards of concrete is needed for the new sidewalk.
To calculate the number of cubic yards of concrete needed for the new sidewalk, we need to multiply the three given measurements: width, length, and depth.
1. Convert the width from feet to yards:
Since 1 yard = 3 feet, divide the width, which is 5 feet, by 3 to convert it into yards:
Width in yards = 5 ft / 3 = 1.66 yards (rounded to two decimal places)
2. Convert the length from feet to yards:
Similarly, divide the length, which is 160 feet, by 3 to convert it into yards:
Length in yards = 160 ft / 3 = 53.33 yards (rounded to two decimal places)
3. Convert the depth from inches to yards:
Since 1 yard = 36 inches, divide the depth, which is 3 inches, by 36 to convert it into yards:
Depth in yards = 3 in / 36 = 0.08 yards (rounded to two decimal places)
4. Multiply the three conversions to calculate the volume:
Volume = Width x Length x Depth
Volume = 1.66 yards x 53.33 yards x 0.08 yards
Volume ≈ 6.676 cubic yards (rounded to three decimal places)
Therefore, approximately 6.676 cubic yards of concrete are needed for the new sidewalk.
