13*13*6=1014 yards of cement
You can't have yards of cement in that sense. You need yards cubed. Convert all the feet measurements to yards and then multiply then together V= l w h
To calculate the amount of cement needed, first convert the dimensions of the sidewalk into cubic yards. The sidewalk's volume is ( \frac{4}{12} ) feet thick × 3 feet wide × 40 feet long = 40 cubic feet. Since there are 27 cubic feet in a cubic yard, the volume in cubic yards is ( \frac{40}{27} \approx 1.48 ) cubic yards. At $76 per cubic yard, the total cost would be approximately ( 1.48 \times 76 \approx 112.48 ).
To calculate the amount of materials needed for a concrete pad measuring 16 feet by 12 feet and 4 inches thick, first convert the thickness to feet: 4 inches is approximately 0.33 feet. The volume of the pad is 16 ft × 12 ft × 0.33 ft = 63.84 cubic feet. Generally, a cubic yard of concrete requires about 1 part cement, 2 parts sand, and 3 parts gravel. For this volume, you'll need approximately 2.36 cubic yards of concrete, which translates to about 0.39 cubic yards of cement, 0.78 cubic yards of sand, and 1.17 cubic yards of gravel.
