How much would it cost to pour a concrete slab for a patio 14 feet by 16 feet and 6" thick if cost is $80 per cubic yard.
I know 27cubic feet equals 1 cubic yard, so do I take 14*16 *27 or??
You can calaculate the number of cubic feet, (1/2)*14*16 = 112, and then divide the result by 27 ft^3/yard^3 to get the number of cubic yards.
Then multiply the number of cubic yards by $80.
To calculate the cost of pouring a concrete slab for a patio, you need to determine the volume of concrete required and then multiply it by the cost per cubic yard.
First, calculate the volume of the slab in cubic feet by multiplying the dimensions: length × width × thickness.
In this case, the dimensions are 14 feet (length) by 16 feet (width) by 6 inches (thickness). However, we need to convert the thickness from inches to feet by dividing it by 12: 6 ÷ 12 = 0.5 feet.
So, the volume of the slab in cubic feet is: 14 × 16 × 0.5 = 112 cubic feet.
Next, convert the volume from cubic feet to cubic yards. As you mentioned, 1 cubic yard is equal to 27 cubic feet. Therefore, divide the volume by 27 to get the volume in cubic yards: 112 ÷ 27 = 4.148 cubic yards (rounded to 3 decimal places).
Finally, multiply the volume in cubic yards by the cost per cubic yard to obtain the total cost. In this case, the cost is $80 per cubic yard, so: 4.148 × $80 = $331.84 (rounded to the nearest dollar).
Therefore, it would cost approximately $331.84 to pour a concrete slab for a 14-foot by 16-foot patio that is 6 inches thick, assuming a cost of $80 per cubic yard.
