Since the title of the question is How do I convert a decimal number to a list of octal digits in Common Lisp?, I think it's worth considering some options that don't use truncate, since that might be sort of expensive (e.g., see Improving performance for converting numbers to lists, and base10 to base2, and the observation that using binary arithmetic instead of quotient and remainder is faster).
Fresh concrete can weight about 3700 lbs for every cubic yard. The density will also determine how much is its weight. assuming its weight to be around 150 lbs for per cubic f â¦ eet. This would make it around 4000 lbs which could come to 2 tons.
1 Cubic Yard of Sand can weigh between 2,600 to 3,000 lbs. or up to one and a half tons approximately. 1 Ton of Sand will cover between 80 to 100 square feet at a 2 inch depth approximately. 1 Cubic Yard of Gravel can weigh between 2,400 to 2,900 lbs. or up to one and a half tons approximately.
