Specific surface area -LRB- SSA -RRB- is a property of solids defined as the total surface area of a material per unit of mass , -LRB- with units of m ²  /  kg or m ²  /  g -RRB- or solid or bulk volume -LRB- units of m ²  /  m ³ or m − 1 -RRB- .. solid. solid. surface area. surface area. mass. mass. volume. volume. It is a derived scientific value that can be used to determine the type and properties of a material -LRB- e.g. soil or snow -RRB- .. soil. soil. snow. snow.
