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. 😂😂😂

Hloo ji
I need ur help please 😢
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😊
You are best teacher in the world❤❤
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
Surface area is 160 CM ² and volume is 128cm³ 1:16:37

Finally We Completed Before Pre Board Examination...😅❤
1:14:18 When two cubes are joined end to end, the faces where they are joined are no longer exposed. This means we should exclude those two faces from the total surface area. Am I Right ?
1:58:46 The value of n will be 100.
Therefore, no. of lead shots = 100
Yessss
01:28:08 - sir maine apka answer calculate kiya to voh 218.064 aa raha hai but
Jab maine khud ke tarike se kiya to mera answer 217.602 aa rha hai to kya iss answer ko approx main likh sakte hai ❓
1:12:07 sir cant we do it this qs vs TSA of Cylinder - TSA of Cone . By Doing it I am Getting my TSA of Solid = 18.2 cm and bh doing the nearest point i am getting 18cm As Urs??
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. 😂😂😂
Sir aapka Sara concept clear hoogya hai please ek video case study ke liye laa dooo
19:18 diagonal of cube =a√3 😊
Sir also correct,
only i support your confusion
No it's √3a
@@Z_ainul both correct only you confused in √2a or a√2

ritik sir se acha koi math padha sakta hai kya
Ritik siirrrrrr ❤
Amazing session sir , this was so practically explained that we could never forget these formulas now
1:01:32 sir ismein 77/2 hoga instead of 77/4
Ha bhai shi kha
