Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 11 feet by 11 feet by 3 inches for a patio if the concrete costs $63.00 per cubic yard?
First, convert all measurements to yards:
11 feet = 3.67 yards
3 inches = 0.25 yards
Now, calculate the volume of the slab:
Volume = length x width x depth = 3.67 yards x 3.67 yards x 0.25 yards = 3.36 cubic yards
Next, calculate the cost:
Cost = volume x price per cubic yard = 3.36 cubic yards x $63.00 = $211.68
The cost to pour the patio slab would be $211.68.
The answer choices are
$211.75
$70.58
$317.63
$1,905.75
Let's take a look at the calculations again to find the correct answer:
Volume = 3.67 yards x 3.67 yards x 0.25 yards = 3.36 cubic yards
Cost = 3.36 cubic yards x $63.00 = $211.68
Based on the calculations, the closest answer choice to $211.68 is $211.75. Therefore, the correct answer is:
$211.75
