If the original building is 810 meters tall, what was the scale used to make the model?

To determine the scale used to make the model, we need to compare the height of the original building with the height of the model.

Let's assume the height of the model is M meters.

The scale can be calculated using the following formula:

Scale = Height of the model / Height of the original building

In this case, the height of the model (M) is unknown, and the height of the original building is 810 meters.

So the formula becomes:

Scale = M / 810

To find the scale, we need to know the height of the model (M). Can you provide that information?

To calculate the scale used to make a model, you need to compare the size of the model to the size of the original object. The scale is typically expressed as a ratio or fraction.

In this case, we know that the original building is 810 meters tall. Let's assume that the height of the model is represented by 'x'.

To determine the scale, we can set up a proportion:

Original building height / Model height = Scale

Given:
Original building height = 810 meters
Model height = x meters

So, the proportion becomes:
810 / x = Scale

Now, we can solve for 'x', which represents the height of the model. Multiplying both sides of the equation by 'x' gives us:

810 = x * Scale

To isolate 'x', we divide both sides of the equation by 'Scale', resulting in:

x = 810 / Scale

Therefore, the scale used to make the model is given by the reciprocal of the fraction or ratio x:810.
