Math Problem Statement

An artist built a scale model of a skyscraper using a scale in which 3 centimeters represents 45 meters. The height of the skyscraper is 360 meters.

What is the height of the scale model in centimeters?

Use the drop-down to complete the sentence.

The height of the scale model is (Select)28162432

(Select) 

  centimeters.

Solution

We know that 3 centimeters represents 45 meters in the scale model.

To find the height of the model corresponding to 360 meters, we can set up a proportion:

3cm45m=xcm360m\frac{3 \, \text{cm}}{45 \, \text{m}} = \frac{x \, \text{cm}}{360 \, \text{m}}

Now, solve for xx:

x=3×36045=24cmx = \frac{3 \times 360}{45} = 24 \, \text{cm}

So, the height of the scale model is 24 centimeters.

Would you like further details on this? Here are some related questions:

  1. How would the model height change if the skyscraper were taller?
  2. What would the model height be for a 500-meter skyscraper using the same scale?
  3. If the scale was changed to 1 cm representing 10 meters, what would the model height be?
  4. How does the concept of a scale model help in architectural planning?
  5. What is the actual height of a 1-meter model using this scale?

Tip: Always set up a proportion to solve problems involving scale models.
