20 inches

Answer 2

20

Explanation:

You can easily get the answer by using the scale (1 inch: 8 ft) in order to know the value of 160 feet to inches.

Let's solve.

160 feet x
`(1 inch)/(8 feet)` =
`(160 feet)/(8 feet)`= 20 inches

Basing it on the scale, the value of 160 feet is 20 inches. This means that the model of the lighthouse is 20 inches tall.

In the final answer, the unit was removed because the problem asked not to put units in the answer.
