  1. volume = 6x6x2 ft^3
    convert that to cubic metres:
    1 ft = .3048 m
    1 ft^3 = .3048 m^3
    multiply 72 by .3048^3 = ...
    multiply that by $30

  2. find the volume of the box ... length times width times depth
    ... remember the conversion factor for feet to meters (multiply EACH dimension)

    find the cost of the sand by multiplying the volume (in cubic meters) by the price
