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.
Since there are 27 cubic feet per cubic yard (3'/yard Ã 3'/yard Ã 3'/yard) you would need to divide the cubic foot volume by 27. Volume = 8628.5 cubic ft. Ã· 27 cubic ft/cubic yd. = 320 cubic yds.To calculate the weight of material needed for a project you will need to know the compacted density of the material.olume = 8628.5 cubic ft. Ã· 27 cubic ft/cubic yd. = 320 cubic yds. To calculate the weight of material needed for a project you will need to know the compacted density of the material.
