Question

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab that is 17 ft by 17 ft by 2 ft if the concrete costs $40.00 per cubic yard?

Answer 1

$856.30 is the answer that guys other answer down there his answer is wrong but it was close I guess.

Answer 2

To solve for how much it would cost, we have to solve for the volume of the slab first, then multiply it by the given price of concrete.

Solving for the volume of the slab:

Since the given price is in cubic yard, it is easier to convert the given measurements from feet to yards first. Using the relation: 1 ft = 0.333 yd:

17 ft = 5.67 yards
2 ft = 0.67 yards

17ft x 17ft x 2ft = 5.67 yd x 5.67 yd x 0.67 yd = 21.54 yd^3

Multiplying this by $40.00 / yd^3:

21.54 x 40 = 861.59

Therefore, it will cost $861.59 to pour the slab.
