Surface Area of a Triangular Pyramid | Math with Mr. J

[@MathwithMrJ]

✅ Thanks so much for watching! ✌️✌️✌️ ✅ Something to keep in mind... I used the letter "s" to represent slant height in the formula in the video. An "𝓁" (lower case L, usually in cursive) can also be used for slant height. You will come across both and both are correct.

Thankyou Jesus for teachers like Mr. J, one thang about him he ain't gone take forever to break it down. Gets straight to the point and effective. Thank you so much you've been helping my son and I so much!!🐐

[@Nagwag]

I cannot thank you enough for doing this series for the surface area of all these shapes I sat down with my notebook and understood everything and my finals are tomorrow so because of this I have a much higher expectation for myself and feel more confident. But its sad to see that students have to go out of their way to find KZbin videos on how to do things because some teachers suck at teaching nowadays

What’s the point of math? Im literally in tears right now because this is so head aching and whats the point of this if I don’t want to be a builder too

Its okay bro/girl I know it might be hard and you may not be good at this but you should never give up on your dreams,I'm probably too late but if you ever have a math class again, ask for help❤

Math is used in everything

You honestly have no idea how much this helped me. My RSM homework had many Lateral area problems with slants and I did not understand what the heck was happening. You not only helped me understand a big geometry concept, but brought my homework grade from a 63 to a 100, as well as keeping as one of the smartest in my class :)

[@pierceanderson8640]

I love in this video how he shows all of his work. They’re people out there that just put the answer and you don’t know how they got the answer and that’s where confusion starts. So I think it’s good to show the work and how he did it.

[@toastedbread909]

Thank you Mr. J! This made me see clearly what to multiply in order to get the answer. You made me think about this in a different way. I have a math test tomorrow for 7th grade, and I'll update you what I get ASAP

Thank you so much for this video. I was struggling to do this because I didn’t even know how to approach it! ❤😂

Thanks so much!! I can’t explain how greatful I am for this channel. Your the reason I’m smart😊

You are so amazing! When I have math homework and search up how to do it I go to your youtube because you explain it so easy!

Hi I'm looking for the formula for the surface area of an IRREGULAR triangular pyramid. Do you have a video like that? Thank you.

[@ShakirFazal-os4lv]

I recommend getting ten dollars and paying for an ixl account where it has many videos

[@yanyanulan]

Please Mr. J. I beg you to post a video about the surface area of a square pyramid 😭 It's just so hard to understand 😢

[@200PM]

A square pyramid is the same formula, except that you don't multiply the area of the base by 1/2. So if your given 1 side length to be 4 inches for example, the area of the base would be 16 since all sides of a square are equal length. A triangle is half of a square hence why the step to multiply by 1/2 or divide by 2 is added.

[@yanyanulan]

Thanks bro. I've just watched the video about the surface area of square pyramid in this channel. Thanks again 😄

[@dudewhatthe2632]

Just asking, how do you multiply a decimal and a decimal together. It's very hard.

[@1988tren]

thank you!!!!! 🎉

[@lulamalurh6112]

So how did you find 9 on that slant height

[@Fli-s2h]

hey mr j :)

[@garyjohnson2635]

Where’s your tie ?😀 Summer more casual ?

[@roseevine5866]

Respectfully, are you sure you multiplied correctly when you found the area of the base? (I'm unsure because I got another answer, 10.825)

[@Jade-om1fi]

He rounded to the nearest hundredth
