Answer 1

Answer:

Lateral surface area of cuboid = 2 h (l + b) ... (c) Total surface area of cube = 6a2 ... The radius of a sphere is 2r, then its volume will be. (A). 3.

Step-by-step explanation:

Answer 2

hey there !

CUBOID:

Total Surface Area of a Cuboid = 2(lb + bh + hl)

Surface Area of a Cuboid = 2h(l + b)

Volume = lbh

CUBE:

The Total Surface Area of a Cube = 6a²

Lateral Surface Area = 4a²

Volume = a³

CYLINDER:

The Total Surface Are of a Cylinder = 2π×r(r+h)

The Curved Surface Area of a Cylinder = 2πrh

Volume = πr²h

CONE:

The Toatl Surface Area of a Cone = πrl+πr²

The Curved Surface Area of a Cone = πrl

Volume = πr²h×⅓

SPHERE:

The Total Surface Area of a Sphere and Curved Suface of a Sphere are same

= 4πr²

Volume = 4/3 πr³

HEMI-SPHERE:

The Total Surface Area of a Hemisphere = 3πr²

The Curved Surface Area of a Hemisphere = 2πr²

Volume = 2/3 πr³
