A shelf measuring 2 feet by 3 feet has a surface area of 6 square feet.
Each of your boxes is 1 foot by 1 foot (12 inches x 12 inches).
You can fit only 6 boxes onto your shelf in a single layer.
The layer underground where there are no empty spaces for water or air is known as the impermeable layer. This layer prevents the movement of fluids such as water or air because it is tightly compacted and does not allow permeation.
Impermeable Rock
The layer underground with no empty spaces for water or air is called the impermeable layer. It acts as a barrier preventing the movement of fluids or gases through it. This layer can consist of materials such as clay, shale, or compacted rock.
The number of banker boxes that can fit on a pallet depends on the size of the boxes and the dimensions of the pallet. Standard pallets are typically 40 inches by 48 inches. If each banker box measures around 12 inches by 15 inches and you stack them, you could fit approximately 20 to 30 boxes per layer, depending on how they are arranged, and several layers high, depending on weight limits and stability. Thus, a rough estimate could range from 100 to 300 boxes per pallet.
There are various measures taken. Ban on CFC's is one of them.
zone of saturation
They are shipped in boxes on a fibre card layer between fruit layers
Some measures that are taken for the preservation of the ozone layer are:Plantation of tressReduction of products containing CFC's like deodorants, spray cans etc.
Impermeable Rock
The measures to be taken include prevention of use of CFc's. they can cause ozone to deplete.
Various steps are being taken to aviud damage of ozone layer. These are the reduction of the ozone depletion chemicals such as cholofloro carbons which can cause huge damage to the ozone molecules present in the ozone layer.
The depletion of ozone layer is measured in PPM. Here PPM is called as Parts Per Million.
