Mercury · Answer

volume of square pyramid A = (1/3)s^2 * h
where s is the length of one of the sides on the bases, and h = height

volume of square pyramid B = given, 3,136 cubic inches

"how many times bigger is the volume of pyramid B than pyramid A"? translates to

(volume of B - volume of A)/(volume of A)
