To calculate the number of 80 lb bags of concrete needed for a 4ft by 4ft area at 5 inches thick, first determine the volume in cubic feet. The volume is 4ft x 4ft x (5/12)ft = 6.67 cubic feet. An 80 lb bag of concrete typically yields about 0.6 cubic feet, so you would need approximately 11 bags (6.67 ÷ 0.6 ≈ 11.11). Thus, you'll need 11 bags of concrete.
U need 1.63 80lb bags per square ft so 131bags to do 8ft by 8ft
To determine how many bags of quick mix concrete are needed to cover 144 square feet, you first need to know the thickness of the concrete layer you plan to pour. For example, if you are pouring a thickness of 4 inches (0.33 feet), you would need approximately 1.33 cubic yards of concrete. Since one bag of quick mix concrete typically covers about 0.6 cubic feet, you would require around 40 bags (1.33 cubic yards equals about 36 cubic feet, and 36 divided by 0.6 equals 60 bags) to cover that area at that thickness. Adjust the number of bags based on the desired thickness.

If your pour to a standard 4-inch depth, you will need 3.54 Cubic Yards.
55.56 cubic yards.

3,800 square feet at a 4-inch depth requires 46.91 cubic yards.
To find out how many yards of concrete you need for your 450 sq ft patio, you would first need to determine the thickness of the concrete you plan to pour. Let's assume a standard 4-inch thickness. One cubic yard of concrete would cover 81 square feet at a 4-inch depth. So for a 450 sq ft patio at 4 inches thick, you would need approximately 5.56 cubic yards of concrete.

you are going to want at least a 6 inch base of packed stone, then at least six inches of concrete reinforced with either rebar or highway rated mesh.
