I am assuming you are trying to find the volume. The formula for the volume is w x h x l. so the answer would be 11 x 1 x 22 = 242 cu. inches. now you have to convert this to liters. the conversion from cubic inches to liters is { 1 cubic inch = 0.016387 liter} so 242 cu inches = 3.965 liters of bedding
