  1. block volume = one yd * one yd * 1/6 yd = 1/6 cubic yard.

    So … six blocks per cubic yard of concrete.

  2. six is the answer

    number of cubic feet in a cubic yard = 27
    number of cubic inches in cubic foot = 1728
    so..
    number of cubic inches in a cubic yard = twenty seven * 1728 = 46656

    Each block is thirty six * thirty six * six = 7776 in^3

    46656 in^3 / 7776 in^3 = six blocks
