I realize this is basic stuff below all of you but am I going crazy is here, or is 13*sin(62) = 11.47831 and not 3.8 ....

sin(60 degrees) is 1/2.

But anyway the problem clearly and repeatedly says horizontal, the box isn't accelerating into the air. That component is presumably getting canceled out by gravity.

Nevermind brah, it's us who have the low IQs. The professor simply forgot to write that he divided the 13sin62 by the mass of the block.

13sin62 = 11.47
11.47/3 = 3.8

He's right.
