Question

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 17 feet by 17 feet by 2 inches for a patio if the concrete costs $40.00 per cubic yard? a. $76.45 b. $71.36 c. $90.67 d. $87.56

Answer 1

The answer will be B ($71.36)

Explanation:

17 ft. = 17/3 yd.

2 inch. = 2/(12 x 3) yd.

The cost will be: 40 x (17/3) x (17/3) x (2)(12/3) = 5780/81 = $71.358024...

= $71.36 (rounded)
