B) how much volume it has.
C) its color.
D) its chemical composition.

Question

Quizplus · Accepted Answer

The total amount of radiation emitted by a heated blackbody depends on its temperature and surface area, according to the Stefan-Boltzmann law. The color and chemical composition do not affect the total radiation emitted by an ideal blackbody, and while volume influences the amount of matter, it is the surface area that directly impacts radiation emission.
