Henri watches a movie that is 3.5 hours, so he spends 3.5 x 60 = 210 minutes watching the movie.
He then watches another movie that is 1.5 hours, so he spends 1.5 x 60 = 90 minutes watching the movie.
In total, Henri spends 210 + 90 = 300 minutes watching movies.
He has 8 hours, which is 8 x 60 = 480 minutes, to watch movies and read.
So, Henri has 480 - 300 = 180 minutes left to read.
If Henri can read 10 words a minute, then he can read 10 x 180 = 1800 words before his free time is up.
#### 1800
The answer is: 1800
