The Volume of PYRAMID A is 8 times greater than the Volume of PYRAMID B as obtained by taking the ratio of the volume of both pyramids.
Volume of a square based pyramid is given as :

Where; h = height ; a = base edge
Hence, Volume of PYRAMID A :

Volume of PYRAMID B = 3,136 in³
Divide Volume of pyramid B by pyramid A :

= 8 times
Expressing as a percentage, multiply by 100% ;
8 * 100% = 800%
Therefore, The volume of PYRAMID B is 800% times GREATER THAN that of PYRAMID A.
