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.)

You will need 414.14 cm squared packages of stickers.

You will need 7 packages of stickers.

Answer 1

To determine how many packages of stickers are needed, we first need to know the surface area of the door stopper. However, since the answer options provide choices that only vaguely reference the area or number of packages needed, we will assume we need to figure out the surface area based on the packages available. The packages cover 75 square centimeters each.

If you calculate how many packages of stickers are needed based solely on the surface area of 75 square centimeters per package, here's how it would generally work:

1. Divide the surface area of the door stopper by the coverage of one package of stickers (75 cm²).
2. Round up to the nearest whole number, as stickers can only be purchased in whole packages.

Since I do not have the exact surface area of the door stopper, I cannot perform these calculations. But evaluating the given response options:

• If the required number of packages is 6, that would translate to a total area needing coverage of about $6\times 75=450,{\text{cm}}^2$.
• If 5.5 packages were needed, that would correspond to $5.5\times 75\approx 412.5,{\text{cm}}^2$.
• The option of needing $414.14,{\text{cm}}^2$ doesn't refer to a whole number of packages and might confuse users mistakenly.
• If you need 7 packages, that would represent a need of $7\times 75=525,{\text{cm}}^2$.

Without knowing the exact surface area of the door stopper, I recommend choosing the answer matching your calculations based on rounding up to whole packages from the door stopper's surface area you have found. If it's around the 450-525 cm² range, the answers suggest 6 or 7 packages respectively. If the area is around 412.5 cm², then 6 packages would fit best as the closest whole.

Based on response options and typical rounding and sticker pack coverage, if one had to choose, the safest guess would be:

You will need 6 packages of stickers.
