A Mesopotamian wheel. Photo source. One of the reasons why the wheel was invented only at this point in history is due to the fact that metal tools were needed to chisel fine-fitted holes and axles. This leads to the next reason â the wheel was not just a cylinder rolling on its edge. It was a cylinder that was connected to a stable, stationary platform.
2[(12W + d)/(x + d)][(12L + j)/j], and compute the number of screws needed for the frame of the deck with the formula. 4(12L +j)/j. Add the two numbers that you get, and this is the approximate number of screws you will need for the entire deck.You may want to factor in an extra 3%.ext, use the following equation to calculate the total length of deck boards needed to construct the top of the deck, L(12W-x)/(x + d) + L. You can use the simplified form, (12WL + dL)/(x + d). Add up the two numbers found in Steps 3 and 4, and this is the total length of board needed to construct the deck.
Add these two sums together. Then divide 5,280 -- the number of feet in a mile -- by the total you just reached. The formula is (2 x length) + (2 x width) = N. Then take 5,280/N to get the number of laps around the court that equal a mile. Run around the sidelines of the court the number of laps found in Step 2. If the number is not even, for example 21.5, run 22 laps instead of 21 to account for slight variations in movement while running along the lines.
