2. How Many Boxes Can Fit in a 20ft/40ft Container (Case Study)

The number of boxes a container can hold depends on the size of the boxes and how efficiently they are packed.

(1) 20ft Container

Assuming standard-sized boxes (1 cubic meter each):

• 20GP: Around 25-28 boxes

For instance, when transporting electronics, the actual number might be 20-22 due to additional packing materials needed for protection.

(2) 40ft Container

• 40GP: Approximately 55-60 boxes

For furniture, a 40GP container can fit around 55 pieces of standard packed furniture, and efficient packing can increase this number.

3. How Much Does a 20ft/40ft Container Cost? Hiring or Buying?

The cost of containers can vary widely based on condition, age, and location.

(1) 20ft Container

• Buying: $2,000 - $3,000, depending on whether it's new or used, and market conditions.

• Hiring: $75 - $100 per month, usually including basic maintenance.

In different regions:

• East Coast, USA: Higher prices, around $3,000 to buy and $100 per month to hire.
