6 gift boxes are 12.36 inches high
32 gift box are x inches high
This is a proportion question. A proportion is made of 2 equal ratios. If you know 3 parts of the proportion, you can solve for the 4th,
6/32 = 12.36/x Cross multiply
6x = 12.36 * 32 Combine the right.
6x = 395.52 Divide by 6
6x/6 = 395.52/6
x = 65.92
Answer: 65.92
Note
Using a proportion saves you the trouble of finding 1 box and multiplying whatever number you get by 32
