Thank you for helping me not to be as intimidated as I used to be over math.

[@arkisaarkisa4717]

A, B, C
A*B*2=X
A*C*2=Y
B*C*2=Z
Surface Area = X+Y+Z

Thank you Josh, this is another lesson for us RUclips viewers to relearn maths a better way.

So much easier and faster than multiplying and adding each side.

What are the chances I have a test on this in a couple of hours

Good luck

I’m gonna ace my test now

Somehow I'm seeing a glass ceiling of learning. I feel it's more simple to do the 3 multiplication with spatial awareness? I get that different horses do better on different courses....

[@thesupadupadude]

Finally! I understand.

Easy

At the end why do you multiply by 2??😅

[@Whatdoyouwantfromme255]

Let's all be honest. We came here after crying at maths

I use the exact same method just faster

This might save you 30 seconds from doing it the normal way. Where in life is it valuable to be able to do this calculation that quickly? Is there a high paying job somewhere where you're asked to compute the surface area of 100s of boxes a day? This video is ridiculous

Oh do shut the hell up.

Is there a high paying job that gets you hand draw pie graphs? Add fractions?
Could save time at school though.

[@DillPicklePatrick]

No, the video is exactly what it promised to be. Is there a high paying job for wasting your own time to tell someone their resources are ridiculous because you didn’t like them? Didn’t think so, yet you still did it. This comment is ridiculous.

[@tusharchilling6886]

I would rather use normal formula than use this complicated trick

[@tecmath]

Cool. That's the best thing - you can choose which way you like best.
Thanks for your comment.
