The curve under the map shows how large a percentage of the total area of the ice sheet has seen melting. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases. Soap films are minimal surfaces. The area of wire surface was determined by establishing the number of diamonds in a square foot of fabric and. The recommended size of the Safety Area in Table 4-1 is increased if the TLOF perimeter is not marked. The surface area [math]A(l)[/math] of the prism is.
