A microwave is placed on top of two boxes. One box is 2 feet 10 inches tall, the other box is 4 feet 9 inches tall, and the microwave is 3 feet 8 inches tall. How tall are they combined? 7 feet 27 inches

You just simply add the feet together (2+4+3) to get 9 ft.

Then, you would add up the inches (10+9+8) to get 27 in., which is 2.25 ft.

Add the feet together and your answer is 11.25 ft.

Hope I answered your question!
