To calculate the volume of the space, multiply the dimensions: 18 ft × 18 ft × 8 ft = 2,592 cubic feet. An 80 lb bag of Quikrete typically fills about 0.6 cubic feet. Therefore, to find the number of bags needed, divide the total volume by the volume per bag: 2,592 cubic feet ÷ 0.6 cubic feet/bag = 4,320 bags. You will need approximately 4,320 bags of Quikrete to fill the space.

To convert the weight of the sand into a volume and find out how much you need you would need to know the density of the sand as the more dense it is the less sand there will be in a 50lb bag and the more bags you would then need to fill the yard

To determine how many ten-pound bags of ice will fill a 48-quart cooler, we first need to convert quarts to pounds. A quart of ice weighs approximately 2.2 pounds, so a 48-quart cooler can hold about 105.6 pounds of ice (48 quarts x 2.2 pounds/quart). Dividing this by the weight of a ten-pound bag of ice, you would need about 10.56 bags, which means you would need 11 bags to fill the cooler completely.

80# bags are 0.6 cubic feet and it takes 41 to make a cubic yard. In that case, 60# bags must be 0.45 cubic feet and it would take 55 to make a cubic yard.

There are approximately 27 cubic feet in a cubic yard, and an 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need about 45 bags of 80-pound concrete.
To fill a 3'x3'x3' hole, you first need to calculate the volume, which is 3 feet x 3 feet x 3 feet = 27 cubic feet. An 80 lb bag of concrete typically yields about 0.6 cubic feet when mixed. Therefore, to fill the hole, you would need approximately 45 bags of 80 lb concrete (27 cubic feet ÷ 0.6 cubic feet per bag).

To fill a 10-inch diameter sonotube that is 4 feet deep, you'll need to calculate the volume of the tube. The formula for the volume of a cylinder is V = πr²h. The radius is 5 inches (0.417 feet), so the volume is approximately 0.544 cubic feet. A typical bag of concrete (60 lbs) yields about 0.45 cubic feet, meaning you'll need about 1.2 bags of concrete to fill the sonotube completely. Therefore, you should plan on purchasing 2 bags to ensure you have enough material.

A 40 lb. bag of soil containing 2 cu.ft.3 will cover 25 sq.ft. @ 1" inch deep. My guess then would be 4 or more -40lb. bags would take care of 24 sq.ft. 4" deep.
The most logical approach for this, would be to purchase a bag of quickcrete, and a few plastic bowls from your local hardware store. Then sit the legs of your dining set into the bowls and fill with quickcrete. this should effectively weigh down your patio set without harming your patio or deck, and without altering the functionality of your patio dining set.
