What is the height of a 10 inch tv when width 8 inch?
The aspect ratio is the ratio of the width to the height. For most TVs, the aspect ratio is 16:9. This means that for every 16 units of width, there are 9 units of height.
So, if the width of the TV is 8 inches, the height can be calculated as follows:
```
height = width / (aspect ratio)
height = 8 inches / (16/9)
height = 8 inches * 9/16
height = 4.5 inches
```
Therefore, the height of the 10 inch TV is 4.5 inches.
