hope you'll understand... XD

Answer 2

Here is your answer ⤵⤵⤵⤵

Curved Surface Area of :-

➡ Cube - 4a²

➡ Cuboid - 2h(l+b)

➡ Cylinder- 2πrh

➡ Cone - πrl

➡ Sphere - 4πr²

➡ Hemisphere- 2πr²

➡ Frustum - 1(r1+r2)×l

Total Surface Area of :-

➡Cube - 6a²

➡ Cuboid - 2(lb+bh+hl)

➡ Cylinder- 2πr(l+r)

➡ Cone - πrl

➡ Sphere- 4πr²

➡ Hemisphere- 3πr²

➡ Frustum; 1(r1+r1)×l + πr1²+ πr2²

Volume of :-

➡ Cube - a³

➡ Cuboid- lbh

➡ Cylinder - πr²h

➡ Cone - 1/3 πr²h

➡ Sphere - 4/3 πr³

➡ Hemisphere - 2/3 πr³

➡ Frustum - π/3 (r1²+r2²+r1×r2) ×h
