1 gal = 3.8 liters....so 65 gallons = 65 * 3.8 = 247 liters
        
             
        
        
        
Use similar volume to calculate 
which is the (ratio of edges)^3 = (ration of volume) 
so just put the numbers in, let the volume of smaller pyramid be y. 
(3/4)^3 = y/320
27/64 = y/320
y=135in3
