1.)CUBE
~Total Surface Area=6a²
~Curved Surface Area=4a²
~Volume=a³

2.)Cuboid
~Total Surface Area=2(lb+bh+hl)
~Curved Surface Area=2h(l+b)
~Volume=L×B×H

3.)CYLINDER
~Total Surface Area=2πr(h+r)
~Curved Surface Area=2πrh
~Volume=πr²h

4.)CONE
~Total Surface Area=πr(l+r)
~Curved Surface Area=πrl
~Volume=1/3πr²h

5.)SPHERE
~Total Surface Area=4πr²
~Curved Surface Area=Nahi hota bhai Sphere ka C.S.A🫂❤
~Volume=4/3πr³

6.)HEMISPHERE
~Total Surface Area=3πr²
~Curved Surface Area=2πr²
~Volume=2/3πr³

7.)FRUSTUM OF CONE
~Total Surface Area=πl(r+R)+r(r²+R²)
~Curved Surface Area=2πl(r+R)
~Volume=1/3πh(r²+R²+rh)
OR
IF SLANT HEIGHT IS NOT GIVEN-
Slant Height = h²-(R-r)²
Bhai yeh pura under root ke andar hain...
Slant height ke bath kar raha hoon..
