surface areas

Outside face sizes

Surface areas is the plural of surface area, the total extent of the outer boundary of a three-dimensional object.

In geometry and physics, calculating surface areas matters for heat transfer, material costs, and chemical reactions: The surface areas of the particles determine how quickly they dissolve.

The concept applies wherever the size of an exposed boundary affects function.
