Answer
The diver appears to have a height of $~~113~cm$
Work Step by Step
We can use the following formula:
$h' = \frac{h}{n}$
where $h'$ is the apparent height and $h$ is the actual height
We can find the apparent height:
$h' = \frac{h}{n}$
$h' = \frac{150~cm}{1.33}$
$h' = 113~cm$
The diver appears to have a height of $~~113~cm$
