To find the surface area of the door stopper, we need to calculate the total surface area of all sides.
First, calculate the surface area of each side:
- Front and back sides: 16.7cm x 15.9cm = 265.53 square cm (x2 for both sides)
- Top and bottom sides: 16.7cm x 8.9cm = 148.63 square cm (x2 for both sides)
- Left and right sides: 15.9cm x 8.9cm = 141.51 square cm (x2 for both sides)
Add up all the surface areas:
265.53 + 265.53 + 148.63 + 148.63 + 141.51 + 141.51 = 1011.34 square cm
Now, divide the total surface area by the area covered by one package of stickers:
1011.34 / 75 = 13.49
Since stickers can only be purchased in whole packs, you would need to purchase 14 packages of stickers to cover the surface area of the door stopper.
Therefore, the closest answer is: You will need 14 packages of stickers.
