The question asks about the "pyramid shown". In those circumstances would it be too much to expect that you make sure that there is something that is shown?
384 inches squared
Volume = 50 in3
determine the length of one edge of a cube that has a surface area of 864 square inches.
If the base length is 6 inches then the base area will be 9*sqrt(3) = 15.6 cm2, which rounds to 16, not 15. So some of the information provided is patently incorrect and therefore the question has no sensible answer.
