Part A. What would be the luminosity of the Sun if its surface temperature were 3900 K and its radius were 1.5 AU ? Part B. What would be the luminosity of the Sun if its surface temperature were 3900 K and its radius were 7.0 AU ? *I don't understand how to calculate this out. Instructor didn't really cover this.

Write The MATLAB SCRIPT for: An open-top box is constructed from a rectangular piece of sheet metal measuring 10 by 16 inches. Square of what size (accurate to 10-9 inch) should be cut from the corners if the volume of the box is to be 100 cubic inches?
