Ready-mixed concrete is sold by the cubic yard. A landscape contractor wants to form concrete paving blocks?
that r rectangular solid with dimension thirty six inch by thirty six inch by six inch. Assuming there is no waste, how many such blocks can she expect to make from 1 cubic yard of concrete..
1 yard is =36 inch……………
options are below:
block volume = one yd * one yd * 1/6 yd = 1/6 cubic yard.
So … six blocks per cubic yard of concrete.
six is the answer
number of cubic feet in a cubic yard = 27
number of cubic inches in cubic foot = 1728
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
