A wooden door stopper needs to be covered with stickers to match the door for a directing contest. If one package of stickers covers a surface area of 75 square centimeters, how many packages of stickers need to be purchased? Find the closest number to the surface area of the door stopper. Stickers may only be purchased in whole packs.

To find the surface area of the door stopper, we need to measure the dimensions of the door stopper and calculate the total area that needs to be covered with stickers.

Let's say the surface area of the door stopper is 300 square centimeters.

Next, we need to calculate how many packages of stickers are needed to cover this surface area. Since each package covers 75 square centimeters, we can divide the total surface area of the door stopper by the area covered by one package:

300 square centimeters / 75 square centimeters per package = 4 packages

Therefore, 4 packages of stickers need to be purchased to cover the surface area of the door stopper.
