Question

Surface area and volume all formulas frustum, cone , cuboid , cube., Cylinder , sphere and hemisphere

Answer 1

Heya Mate..✍️

Frustum:

Surface area - π l 1 (R+r) +πR 2 +πr 2

Volume - V = (h/3) x (a+b+√ (axb))

Cone:

Surface area - l 2 = h 2 + r 2. l 2

Volume - πr²h/3

Cuboid :

Surface area - 2(lb+bh+hl)

Volume - lbh

Cube:

Surface area - 6a²

Volume - a³

Cylinder :

Surface area - 2πrh + 2πr²

Volume - πr²h

Sphere:

Surface area - 4πr²

Volume - 4/3πr³

Hemisphere:

Surface area- 4πr²

Volume - 2/3πr³

Hope it will be helpful :)
