To calculate the number of 80 lb bags needed for a 3x4x3 pad, first determine the volume of the pad in cubic feet: 3 ft x 4 ft x 3 ft = 36 cubic feet. An 80 lb bag of concrete typically covers about 0.6 cubic feet. Therefore, you would need approximately 36 / 0.6 = 60 bags of 80 lb concrete to fill the pad.
