all formula for surface area volume class 10​

Answer 1

Answer:

all formula for surface area volume

Answer 2

Here's ur answer :

✴ Cuboid

✔volume = (l ×b ×h) cu units.

✔diagonal of Cuboid = √(l²+b²+h²) units.

✔total surface area = 2(lb+bh+lh) sq units.

✔lateral surface area= [2(l+b)×h]sq units.

✔area of four walls= [2(l+b)×h]sq units.

✴ Cube

✔ volume of cube = a³ cu units.

✔ diagonal of the cube = √3a units

✔ TSA = 6a² sq units

✔ LSA = 4a² sq units

✴ Cylinder

✔ volume = πr²h cu units

✔CSA = 2πrh sq units

✔TSA = (2πrh + 2πr²) sq units

✴Cone

✔slant height (l) = √h² + r² units

✔ volume = 1/3πr²h cu units

✔CSA = πrl sq units

✔TSA = πr(l+ r) sq units

✴Sphere

✔volume = 4/3πr³ cu units

✔Surface area = 4πr² sq units

✴ Spherical shell

✔ volume of Spherical shell

= 4/3π(R³ - r³) cu units

✴ Hemisphere

✔ volume = 2/3πr³ cu units

✔CSA = 2πr² sq units

✔TSA = 3πr² sq units

Hope it helps ✔
