# A driveway 18 ft. wide and 36 ft. long is to be paved with concrete 3 in. thick. How many cubic yards of concrete are required?

## V = L*W*h = 36 * 18 * 0.25 = 162 Ft^3

V = 162Ft^3 * 1yd^3/27Ft^3 = 6 Yds^3.

## To find the cubic yards of concrete required, we need to calculate the volume of the driveway.

Step 1: Convert the measurements to the same unit

Since the thickness of the driveway is given in inches, we need to convert the width, length, and thickness to feet.

Width: 18 ft.

Length: 36 ft.

Thickness: 3 in. = 3/12 ft. = 0.25 ft.

Step 2: Calculate the volume of the driveway

The volume of a rectangular solid is given by the formula: Volume = Length x Width x Height.

Volume = 18 ft. x 36 ft. x 0.25 ft.

Volume = 162 ft³.

Step 3: Convert the volume to cubic yards

To convert the volume from cubic feet to cubic yards, divide the volume by 27 (because there are 27 cubic feet in a cubic yard).

Volume in cubic yards = 162 ft³ / 27.

Volume in cubic yards = 6 yd³.

Therefore, 6 cubic yards of concrete are required to pave the driveway.

## To find the answer to this question, we need to calculate the volume of the concrete required to pave the driveway. Here's how you can do it step by step:

1. Convert the measurements to a common unit: Since the width and length are given in feet, we need to convert the thickness to feet as well. Since there are 12 inches in a foot, 3 inches is equal to 3/12 = 0.25 feet.

2. Calculate the volume: The volume can be calculated by multiplying the width, length, and thickness of the concrete. So, the volume is:

Volume = Width × Length × Thickness

= 18 ft × 36 ft × 0.25 ft

3. Calculate the cubic yards: Since concrete is often measured in cubic yards, we need to convert the volume to cubic yards. There are 27 cubic feet in a cubic yard, so dividing the volume by 27 will give us the answer.

Cubic Yards = Volume / 27

Now, let's calculate the answer:

Volume = 18 ft × 36 ft × 0.25 ft = 162 cubic feet

Cubic Yards = 162 cubic feet / 27 = 6 cubic yards

Therefore, you would need 6 cubic yards of concrete to pave the driveway.
