To determine the amount of rebar needed for a 20 x 60 x 8 inch slab, you first need to calculate the perimeter and then the spacing of the rebar. For a typical slab, rebar is usually placed at 12 to 18 inches apart in each direction. Assuming you use #4 rebar (0.5 inches in diameter) spaced at 16 inches on center, you would need approximately 8 pieces of rebar along the 20-inch side and 5 pieces along the 60-inch side, totaling around 13 lengths of rebar, considering overlaps and cut-offs. Always consult local building codes and structural engineers to confirm specific rebar requirements for your project.
You need enough for a little less than 10 cubic feet. You can read how much coverage of cement there is per bag on the bag and determine from there. I had to use 18 bags of ready-mix on a 2 ft by 12 ft by 3,5 in thick slab,
