How do you figure concrete steps? The volume is determined by multiplying the length x width x depth. Once finished, add up the rectangle volumes to find the total volume. Note – since concrete is calculated in cubic yards, you’ll need to convert your volume measurement into cubic yards.
How do you calculate rise and run for concrete steps? To compute the unit rise and run, first divide the total rise by 7 inches, a standard step height. Round up fractional results to the nearest whole number. Then divide the total rise again by this number to get the unit rise.
How do you calculate steps? You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).
