Radiating Surface
Asked by fathima12 | 19 Jan, 2010, 11:04: PM
answered-by-expert Expert Answer

A cube have six faces, if we put hot water to fill completely the volume of the cube, then all six enclosing surfaces are heated and will radiate.

Radiating surface for a cube = 6xArea of one face = 6x2

Consider for cone,

If it's a conical vessel, holding hot water and the vessel is not closed, then the radiating surface is πrl. All other formuale are correct.
