TSA of cube + CSA of hemisphere - area of bottom of hemisphere.

[navkar_jain]

2:19 mam. You write CSA but it is a TSA
and you are the best teacher 😊

[andleebmehraj]

REMINDER:
It's is not CSA OF CUBE it should be TSA.
BECAUSE WE ARE INCLUDING TOP +BOTTOM 🤡

[saarikagururaju]

Mam here CSA of cube is 4a² not 6a² and 6a² is for TSA @class 10 maths and science @mansi mam

[PreetiYadav-mcfi]

mam csa of cube is 4a square so why we take 6a2

[harishpal]

mam qnz me SURFACE AREA likha hota to ye kese pta lgega ki TSA hai ya

[PAGALMGAMING-tbuw]

Mam curved surface area of cube is 4a*2

[Himanksain]

Ma'am aap bhi Kya aadhya ke toys le aaye😂😂

[Suraj_chawla]

#Cube.
C.S.A = 4a²
T.S.A = 6a²
Volume =a³

#Cuboid.
C.S.A = 2h(l+b)
T.S.A = 2(lb+bh+hl)
Volume = l×b×h

#Cylinder.
C.S.A = 2πrh
T.S.A = 2πr(h+r)
Volume = πr²h

#Sphere.
C.S.A /T.S.A = 4πr²
Volume = 4/3πr³


#Hemisphere.
C.S.A = 2πr²
T.S.A = 3πr²
Volume = 2/3πr³

#Cone.
C.S.A = πrl
T.S.A = πr(l+r)
Volume = 1/3πr³


Best of luck for Board 2023 😊

Hii mam you always make a video that helps me a lot

[Manyatrathore]

2:21 Mam that will be TSA OF CUBE not CSA coz we are also including the bottom part

[dvg_beats]

CSA of Cone 4a square
TSA of Cone 6a square

[mansi]

Mam jaha per T.S.A ka formula lgega apne formula thik likha h but C.S.A MISTAKE SE LIKH DIYA

[Tanuverma]

Mam curved surface area of cube is 4a2

[deadman]

The area of the circle is minus because we need the area remaining of the top of the cube as it comes in TSA of cube

[varsharani]

session 2023-2024 all the best for board exam.❤

[chahnas.]

The answer is correct but the way she wrote curved surface area of cube and then wrote the formula of total surface area was totally incorrect

[SajjadNaikoo]

Thanks u so much mam ur video always helps me a lot❤

[ravibn]
