The gravel mix calculator computes the number of bags needed to fill a given cubic dimension. You will need to enter the width, length and depth of the cube. The width and length are specified in feet and the depth is specified in inches. The calculation is for 80lb bags of gravel mix. The calculation is based on the assumption that each bag will fill approximately .66 cubic feet.
