Most commercial backpacks (rucksacks) give their capacity in litres, which is usually unmeaningful to most people. Experience means that the day sack you bought for a Sunday walk, is not big enough for a week of hiking miles from a supermarket or a commercial campsite with a shop. So, basically, your backpack must be of the capacity to suit your needs. Also, from experience, it is better to have a half full backpack than a backpack that is so full of 'essential' equipment that items have to be tied onto the outside of the backpack.
You could be doing an experiment
It would burst.
You could hold a jar, jackknife, jewelry or a jellybean in your hand. They begin with the letter j.
Fill your pack with packing peanuts. Dump them out into a cardboard box and level them out. Measure the width and depth of the box and the height of packing peanuts. For cubic inches, multiply the width, depth and height.
it would be for 4 yeas.
They could be waiting for a better price
800g of water would be 800mL of water, so a liter beaker or graduated cylinder could hold that volume of water.
As a very rough estimate, I would suggest 40 gallons!
This container could hold up to 3,949.71 US gallons of water.

If the atmosphere could no longer hold water vapor, it would result in extremely dry conditions with no clouds, precipitation, or humidity. This could lead to widespread desertification, crop failures, and ecological disruptions due to lack of water availability for plants and animals. Additionally, the water cycle would be disrupted, affecting weather patterns globally.
Assuming the images were in jpg format at 80 % quality (the default), a low estimate would be around 800, and a high estimate would be over 2000, depending on the image's colours.
