The ratio is 27 : 1331.
As volume is length x length x length, cube the ratio of the lengths, thus: Ratio of lengths = 2 : 5 ⇒ Ratio of volumes = 23 : 53 = 8 : 125
274,625. The volume formula is lwh/3, so if the sides are 65x longer, the volume will be (65^3)x larger, or 274,625.

The ratio is 57 cubed. This answer does not depend on the fact that you are comparing two similar pyramids; it works the same for two cubes, two spheres, etc. - in general, for any two similar 3D objects.
The ratio of their volumes is 23^3 = 12167.

The ratio is 27 : 1331.
As volume is length x length x length, cube the ratio of the lengths, thus: Ratio of lengths = 2 : 5 ⇒ Ratio of volumes = 23 : 53 = 8 : 125
274,625. The volume formula is lwh/3, so if the sides are 65x longer, the volume will be (65^3)x larger, or 274,625.
If the ratio of side lengths is 49 (that is 49 to 1) then the ratio of their volumes is 493 to 1, which is 117,649 to 1.
