On a steamy mirror wipe away just enough to see your full face. How tall will the wiped are be compared with the vertical dimension of your face?
How close will you be standing to the mirror?
To determine the height of the wiped area on the mirror compared to the vertical dimension of your face, we need to consider the principles of similarity and proportionality.
Here's how you can calculate it:
1. Measure the vertical dimension of your face. Use a ruler or any suitable measuring tool to determine the distance from the top of your forehead to the bottom of your chin.
2. Wipe away enough steam on the mirror to reveal your full face. Ensure that the wiped area perfectly corresponds to the width of your face.
3. Measure the height of the wiped area on the mirror. Again, use a ruler or measuring tool to determine the distance from the top to the bottom of the cleared portion.
4. Calculate the ratio by dividing the height of the wiped area on the mirror by the vertical dimension of your face. This ratio represents how many times smaller the wiped area is compared to your face vertically.
For example, if the wiped area on the mirror measures 5 centimeters in height, and the vertical dimension of your face measures 20 centimeters, the ratio would be 5/20 = 0.25. This means the wiped area is 0.25 times the height of your face.
So, in conclusion, you can find out how tall the wiped area is compared to the vertical dimension of your face by measuring both and calculating the ratio between them.
