[@georgialuderman6190]

I've been struggling with these questions for a while. Helped so much! Thank you, you're a saviour

Hi! At around 5:50 where did the 44 come from?

[@mathrovert]

44 is the critical number "x" found back at 4:30

[@kidload9x]

good solve but i have a question: at 4:45 you said Cube Root of 85.184 = 44??? i calculated and the result is 4.4

[@lpcustomvs]

he's American, he uses point as a decimal separator, not the comma

[@MrGodofconquest]

where do you get other x squared when there is only 1?!

[@cm6995]

When simplifying for S wouldn't it be (x^3+170368)/x? It made sense the way you did it, I did it the same way but got the wrong answer.

[@ihorpidhirnyy5028]

I was searching for something else while came across your video, but you may know the answer. How would you solve this if base wasn't square but of unknown dimensions.

Great video man! its one of the best ive seen

[@sammorton691]

i'm dumb.

[@sammorton691]

RECTANGULAR PRISMS HAVE 6 FREAKING SIDES WHY DID YOU ONLY ACCOUNT FOR 5 OF THEM???????!!!!!!!!!

[@Mathispower4u]

The directions state it is an open top box, which means there is no top.
