Shipping costs are charged by either dead weight or cubic weight (whichever is greater).
Dead weight = The actual weight of the item. Cubic weight = L x W x H (Meters) x Cubic Conversion Rate (250).
Multiply the height x length x width = 0.35 x 0.65 x 0.4 = 0.091 m³ (Cubic Measurement)
To convert 0.091 m³ to a weight in kilograms: Multiply 0.091m3 x 250 (Cubic Conversion Rate) = 22.75 kg
