Question

Formulas of surface area and volume chapter guys plz send all the formula plzzzz.....

Answer 1

See the image for answer

Answer 2

Hola !


Answer -


Chapter Name - Surface areas and Volumes


Formulas -

T.S.A - Total Surface area.

C.S.A - Curved Surface area.

V - Volume

l - Length ( for cuboid )

l - Slant height (Cone)

b - Breadth

r - radius

h - Vertical height.

1. Cube

T.S.A - 6l^2

C.S.A - 4l^2

We exclude the top and base in the C.S.A or L.S.A. It means area of four walls.


Volume - l^3


2. Cuboid


T.S.A - 2 ( lb + bh + hl )

C.S.A - 2h ( l + b )

Volume - l × b × h



3. Cone


T.S.A - πr ( l + r )

C.S.A - πrl

Volume - 1/3πr^2 h


4. Cylinder

T.S.A - 2πrh

C.S.A - 2πr ( h + r )

Volume - πr^2h


5. Sphere

It has same C.S.A and T.S.A

= 4πr^2


Volume - 4/3 πr^3


6. Hemisphere


T.S.A - 3πr^2


C.S.A - 2πr^2


Volume - 2/3 πr^3



Hope it helps !
