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? (1 point)

$211.75
$70.58
$317.63
$1,905.75

I'll be glad to check your answer.

The answer is $70.58

I got a 5/5. Go Cubs (I'm not from Chicago, I'm from Detroit, but I like the Cubs).

To calculate the cost, we first need to determine the volume of the concrete required for the patio slab.

The dimensions provided are 11 feet by 11 feet by 3 inches. However, it's important to note that all dimensions need to be in the same unit before performing calculations. Let's convert the dimensions to the same unit – feet.

Since 1 foot is equal to 12 inches, we can convert the thickness of the slab from inches to feet by dividing 3 inches by 12:
3 inches ÷ 12 = 0.25 feet

Now we have the dimensions in feet: 11 feet by 11 feet by 0.25 feet.

To calculate the volume, we multiply the three dimensions together:
Volume = 11 feet × 11 feet × 0.25 feet = 30.25 cubic feet

Since the concrete is sold by the cubic yard, we need to convert the volume from cubic feet to cubic yards. Since 1 cubic yard is equal to 27 cubic feet, we divide the volume by 27:
30.25 cubic feet ÷ 27 = 1.12 cubic yards

Now that we have the volume of the concrete required, we can calculate the cost. The concrete costs $63.00 per cubic yard, so we multiply the volume by the cost per cubic yard:
1.12 cubic yards × $63.00 per cubic yard = $70.56

Therefore, the cost to pour a slab with dimensions 11 feet by 11 feet by 3 inches, for a patio, at a cost of $63.00 per cubic yard would be approximately $70.56.

So, the correct answer is $70.58.
