1. 1  possible duplicate of Convert decimal number to octal in Lisp â sds Nov 10 '13 at 17:28. 2  @sds Not a duplicate; the one you refer to is about a wrong use of the T symbol and does not have the reverse problem. 3  Wow, thank you very much. 4  When you use truncate and mod, you get the digits in reverse order (4 4 1).
The estimation of 1 cubic foot weighing 40 pounds is based on bags of topsoil. Some bags state a weight of 40 pounds, and some state a volume of 1 cubic foot. The dimensions of the contents are similar. Other factors determining weight are moisture content and volume of sticks, rocks and other debris.
Best Answer: Standard concrete weighs almost 4,000 pounds per cubic yard. A cubic foot of concrete weighs about 145 pounds. That means you would need roughly 3 bags per cubic foot. There are 27 cubic feet per cubic yard. If you need 6.5 cubic yards, that is 526.5 bags of mix, (3*27*6.5=526.5). Adding water to the mix will increase the weight a little bit, but you'll waste some of that volume in the wheelbarrow and on the ground.
