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 purchase in whole packs.)

Answer 1

First, measure the surface area of the wooden door stopper. Let's say it is 70 square centimeters.

Next, divide the surface area of the door stopper by the area covered by one package of stickers:
70 square centimeters / 75 square centimeters = 0.93

Since stickers can only be purchased in whole packs, you will need to round up to the nearest whole number. Therefore, you would need to purchase 1 package of stickers to cover the door stopper.
