Similar Shapes - Area and Volume Scale Factors | GCSE Maths Tutor

A video revising the techniques and strategies for looking at similar shapes with area and volume. (Higher Only).

This video is part of the Ratio & Proportion module in GCSE maths, see my other videos below to continue with the series.

These are the calculators that I recommend 💎

These are the new revision guides I recommend 💡

[navyaaagrawal]

He is the best math tutor you could ever find guys!!

This video was so helpful as I have a maths test on this topic tomorrow and I was really stressing because I just didn't understand this topic, but now I do and I am confident with area/volume scale factors! Thanks so much 😁

[mooshroom]

see this, the first 4 minutes of the video taught me more than any teacher on earth ever has

I actually learned a lot from this quarantine hitting hard

[emaanmuhammad]

Thanks a lot for taking your time to make these videos and going through everything as clear as you can. 🙂

Omg, finally learnt this topic. I've been so stumped on it. Thank you, congruent shapes are next! ^_^
Good luck to everyone else revising atm

Man, I had that last question on my year 10 mock last year and was baffled by it! Thanks for going over it.

Good video, however, you don't need a calculator for the ratio question (24:07) if you do it in a different way. Find the length SF as a ratio, so cube root 27:64 = 3:4. Then square to get ASF which becomes 9:16. Do 800/16 = 50, finally 50 x 9 = 450. Easier in my opinion :)

precise and accurate explanation, learned easily without any difficulties, many thanks for this video

[lolayearsago]

Thank you so much. I was so confused on this topic but you explained it really well. I can’t thank you enough sir.

Please please could you make a video on congruency? These have really helped me improve a lot and I would appreciate it if the congruency vid was out before the end of September before my mocks. Thank you

[Sophia-urnb]

Could you make a video on Volume and surface area of cones and spheres?

For the ratio question at 27:64, there a much faster way to do it. You can just keep everything in fractional form and use fractional indices to convert from vsf to asf and divide 800 by the asf:

vsf = 64/27
therefore, asf = (64/27)^2/3 - this is the same as cube rooting it then squaring it.
800 ÷ (64/27)^2/3 = 450

man I got a 5 in my eoy y 10 test cus my mental health was pretty bad and studying didnt even cross my mind at that point, over y11 i used your channel alot and in igcse past papers ive been getting 8s in paper 4s and 9 in paper 2s, tomorrow i have my mock paper 2, ill update this comment.
