Explanation:
To find the scale factor, we need to determine how many times larger the actual object is compared to the model.
First, we need to convert the units of measurement so that they are the same. Let's convert 324 feet to inches by multiplying by 12 (since there are 12 inches in a foot):
324 feet x 12 inches/foot = 3,888 inches
Now, we can calculate the scale factor by dividing the actual height of the object by the height of the model:
3,888 inches / 6 inches = 648
Therefore, the scale factor is 648. This means that the actual object is 648 times larger than the model.
