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:
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
