To solve this problem you must apply the proccedure shown below:
You have that the scale model of the building has a height of 18 inches and a length of 14 inches and the height of the real building is 360 feet. Therefore, you have:
18 inches=1.5 feet
14 inches=1.16 feet
1.5 feet-----360 feet
1.166 feet----x
x=279.84 feet
The answer is: 279.84 feet
