1 answer

Let's set up a proportion using the given information:

x = height of the model of the Altar Stone
4.9 = height of the original Altar Stone

Using the scale of 3 : 5, we can set up the proportion:

3/5 = x/4.9

To solve for x, we can cross-multiply:

5x = 3 * 4.9
5x = 14.7

Divide both sides by 5 to isolate x:

x = 14.7 / 5
x = 2.94

Therefore, the height of the model of the Altar Stone is approximately 2.94 meters.
