A one door stopper needs to be covered with stickers to match the door for directing content. If one package of stickers covers the surface area of 75 cm 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
You will need 414.14 cm 2 packages of stickers
You will need six packages of stickers
You will need seven packs of stickers
You will need 5.5 packs of stickers
You will need 7 packs of stickers.
To calculate the surface area of the door stopper, you need to add up the surface areas of each side:
16.7 cm x 5 cm = 83.5 cm^2
8.9 cm x 5 cm = 44.5 cm^2
15.9 cm x 5 cm = 79.5 cm^2
Total surface area = 83.5 cm^2 + 44.5 cm^2 + 79.5 cm^2 = 207.5 cm^2
Since one package of stickers covers 75 cm^2, you will need to cover approximately 207.5 cm^2 of the door stopper.
This means you will need 3 packages to cover 225 cm^2, which is the closest number above 207.5 cm^2. Therefore, you will need 7 packs of stickers.
