This was very informative. Why do textbooks make it seem so complicated?
cuz you have to read it. its easy when somrbody who knows what theyre doing is explaining it
Yah and my teacher makes it so confusing
@@paigewinters6048 ikr
Teachers jst torture us instead of explaining
because it’s complicated
Really helpful video. I liked the trick with using the vertex to see what you have already worked out.
I am binging on these videos because I have a test in a few hours and I am panicking
gl! lol this comment gotta a reply after four years XD
@@aseelzakar.x4332 XD glad to know im not the only one still watching this

How did it go?
This guy's voice... British/Australian voices = the only reason i can learn anything.
True Indeed.
Yep it's not a hard to understand accent like Indian
Yeah its Australian
you can tell it's Australian cos he says "gooday"
No he is bruce the shark from finding nemo
Aight thank you. My class is too loud and my teacher struggles to teach us, so it makes it hard to focus in class.
RiftOnly Yep Noisy classes hey
I have the same in my class. ;/
At least y'all teacher's try mine is always on the phone
Thus is why I’m home schooled
thanks i needed this for my year 9 test
i had no idea how to find the surface area for my homework and i was extremly frustrated and you have helped me sooo much thank you.

Thanks for explaining the total surface area!👍👍👍👍
I am so glad I looked up a video for this. My teacher is giving use these formulas that make it 10 times harder to understand. Great video! I need to show this to her.
1 part of cheat sheet done... 3 more things to go! :( thanks man youre really helpful :)

My teacher spent almost all month to teach this and you did it in 16min LOL
thank you so much i was about to cry cause i didn't understand
Omg I never realised how easy this could be thank you so much 😊
I love how simple u keep things👍
Just a suggestion you can just times the area of the square by 2 because theres 2 square bases and then times the area of the rectangle by four for the same reason
really helpful and I like how to keep it simple and easy Thank you for making this video
Thanks u very much. I have a test coming up and I rlly needed this!
Great video, really helped me prepare for my Exams. Keep up the great work.

Thank you middle aged Australian man
THANK YOU SOO SO MUCH!!! This video helped a lot keep up the great work ❤️❤️❤️❤️❤️❤️
I got confused on the triangular prism
Blue Tube do that method but divide it by 2 because if you just leave it that will be the surface area of a cuboid but if you divide it by 2 that will be a triangle

@@vaugnstein6537 thanks for the explanation really helpful
THANK YOU SO MUCH! THE X2 WAS THE THING I WAS MESSING UP ON! THX VERY MUCH!
This helped so much I'm so thankful they made this video
Good video. I liked how clear it was.
LW LH HW times those and add them up. x2 the final answer after finding the sum in LW LH HW. then put m2 or cm2
Edit:rectangular prism

7:07 - why didn't you halve the 6cm (height of triangle), like you halved the 8cm for the base?
Because the height isn't halved in the equation. Only the base is
