Rhitik sir i don't know if u will see it or not but all i wanted to say was that i was a really bad student till 9th grade like i got 3 marks in maths to give a hint but whenever i asked my teachers doubt they were always telling that u have learnt it in 5 class and 7,8 class but i was not studying at that time too so i was always behind but watching ur teaching way from the basic has brought to the level i wanted to be and now i am not scared of any exam and i do not think now of hiding 5 minutes before the school bus comes 😂😂 thank you ❤

19:19 pe sir ne kyaa kiyaa jisko samajh nahi aaya vo plzz look 👇 Pythagoras theorem se niche vaale rectangle kaa diagonal hogaa... L²+B²=H² H=±√{L²+B²} HERE we take only + side number because side is never in minus so side is √{L²+B²}....EQ 1. Now Sir tak another side that's diagonal is H²+h²=D²... (h is hight of 3d cuboid, H is √{L²+B²} BY EQ NO .1 AND D IS DIAGONAL OF CUBOID ) . Now, put value of H in the value of D² so we get. D²=(√{L²+B²})²+H² D²=L²+B²+H²....[(√L²+B²)²=L²+B²] D=±√[L²+B²+C²] . HERE AGAIN WE'RE NOT TAKE THE MINUS SIDE SHOULD WE TAKE ONLY PLUS SIDE THEN WE GET.. D=√[L²+B²+H²]... HENCE IT IS DIAGONAL. 😂😂😂
1:15:00 Sir, I have a doubt: Why would the volume of the resulting cuboid not be equal to 64 + 64 cm3???? Because they are identical and joined together....Please answer

1:01:30 yha pe 77/4 nhi 77/2 aye ga a
Hann brooo firr correct bhi to kiyaa tha sir ji ne😅
Thnk you sir ❤❤ literally mujhe yeh chp nhi aata tha pr aapka video dekhke sare concept aa gye
2:45:50 apparent capacity= 196.25 cm³
Actual capacity=163.55 cm³
1:02:14 silly mistake there
77/2
Yes
At 2:49:25 , ratio of surface area = 1:9
How
@@saloniupadhyay5222 equate the volume and formula of the 2 cubes to find the edge of the cubes then put the value of the edge in the formula of tsa of cubes.
THANKS
Mera bhi itna hi aaya😊
1:17:02 TSA--> 160 cm
Volume--> 128cm³
Best teacher of maths king 🎉🎉🎉
1:50:56 archimedes principal
2:49:28
Solution:-V1/V2=1/27
a1³/a2³=1/27
a1/a2= ³√1/27
a1/a2= 1/3
Now,
TSA=6(a1)²/6(a2)²
Cancel 6&6
(a1)²/(a2)²=1/3
(a1)/(a2)=(1/3)²
(a1)/(a2)=1/9

Thanx bhai
2:31:43 bilkul nhi sir 😂
Exam ke din bhi padhne ka man nhi kar raha 💀
🤦🏾🤦🏾mujhai bhi
Koi 2025 board wala h kya...

2:32:09 154×9×122/5×10×10
yaha pe 10 × 10 se 154 or 122 kat skte the kyuki dono hi 2 ke divisible hain
Toh ye kuch esa hota= 77×9×61/5×5×5
Lekin calculator se calculate krne pe dono hi ki values alag aarhi hai jbki ye dono ekdusre ke simplified version hai
Esa kyu??
my fear of maths gone only because of you babua ❤🩹❤thankyou so much ritik sir 🙏🙏🙏❣
Oh i really want to learn this chapter from you!😭❤️
ritik sir se acha koi math padha sakta hai kya
Ritik siirrrrrr ❤
hello udanians all the best for pre board exams😆
Surface area is 160 CM ² and volume is 128cm³ 1:16:37
Sir aap padate bahut acha ho aur aap bahut handsome bhi ho😅
🌚🌚
Toh aage ka kya plan hai 😅
Pdhle bhen 😂
19:19 pe sir ne kyaa kiyaa jisko samajh nahi aaya vo plzz look 👇
Pythagoras theorem se niche vaale rectangle kaa diagonal hogaa...
L²+B²=H²
H=±√{L²+B²}
HERE we take only + side number because side is never in minus so side is √{L²+B²}....EQ 1. Now
Sir tak another side that's diagonal is H²+h²=D²... (h is hight of 3d cuboid, H is √{L²+B²} BY EQ NO .1 AND D IS DIAGONAL OF CUBOID ) .
Now, put value of H in the value of D² so we get.
D²=(√{L²+B²})²+H²
D²=L²+B²+H²....[(√L²+B²)²=L²+B²]
D=±√[L²+B²+C²] .
HERE AGAIN WE'RE NOT TAKE THE MINUS SIDE SHOULD WE TAKE ONLY PLUS SIDE THEN WE GET..
D=√[L²+B²+H²]... HENCE IT IS DIAGONAL. 😂😂😂
1:01:32 sir ismein 77/2 hoga instead of 77/4
Ha bhai shi kha
hena fr
i thought this was a fake PW channel but its not

Ritika ma'am your entry is always aati Sundar waah...!😂😂😂
हमारी सबसे बड़ी कमजोरी यह है की हम प्रयास करना छोड़ देते है सफलता का एक रास्ता है कि एक बार और प्रयास किया जाये।
Thank you sir! 🙏❤
sir you are the best teacher!
Hardest chapter but MISHRA JI is Brilliant
1:43:34 i gotta continue from here:) reminder...
Complete it 😂
Kon kon January mey dekh raha hey for boards 2024-25 batch vote karo
1 like= 99% in board 🎉🎉
1:02:03 when take 77/2
Answer is --> 1925/3 cm³
-->641.66 cm³ is Answer
Who Pause At 7:02😂
1:15:00 Sir, I have a doubt: Why would the volume of the resulting cuboid not be equal to 64 + 64 cm3???? Because they are identical and joined together....Please answer
If u solve the value of both it is the same but we have to follow the formula and the step we are given
@@mordhvajjaga8599 Ok,thanks
