You will need 7 packages of stickers.
To calculate the surface area of the door stopper, you would need to measure the length, width, and height of the door stopper and calculate the total surface area. Then, divide this total surface area by 75 square centimeters to determine how many packages of stickers are needed. Since stickers can only be purchased in whole packs, you would need to round up to the nearest whole number, which in this case would be 7 packages.
