How to tell they’re full?

The best way to tell if a container is full is to physically check it. If you can’t easily check the container, you can use a variety of methods to determine if it is full. Here are some suggestions:

• Measure the container’s capacity and compare it to the number of items inside. If the number of items exceeds the container’s capacity, it is full. #measure
• Check the container’s weight. If the weight is close to or exceeds the maximum allowable weight, then the container is full. #weight
• Check the container’s height. If the height is greater than the maximum allowable height, then the container is full. #height
• Check the container’s volume. If the volume is close to or exceeds the maximum allowable volume, then the container is full. #volume
