John is putting in a concrete patio in his backyard. The dimensions of it are 12ft by 8ft by 6inches. If concrete costs $6.75 per cubic foot how much will the concrete cost for the patio
V = lwh
V = 12 * 8 * 0.5
V = 48 cubic feet
48 * 6.75 = ?
To calculate the cost of the concrete for the patio, you need to determine the volume of concrete required. The volume can be calculated by multiplying the length, width, and height of the patio together.
Given:
Length = 12 ft
Width = 8 ft
Height = 6 inches
1. First, convert the height from inches to feet:
6 inches = 6/12 ft = 0.5 ft
2. Calculate the volume of the patio:
Volume = Length x Width x Height
Volume = 12 ft x 8 ft x 0.5 ft
3. Multiply the dimensions together to find the volume:
Volume = 48 cubic feet
4. Finally, calculate the cost of the concrete by multiplying the volume by the cost per cubic foot:
Cost = Volume x Cost per cubic foot
Cost = 48 cubic feet x $6.75/cubic foot
Now you can calculate the cost of the concrete for John's patio.
