Explanation:
Cuboid, Cube, Right Circular Cylinder, Right Circular Cone, Sphere and Hemisphere.
Formulae:
Cuboid:
Volume = lbh
Lateral surface / Curved Surface Area = 2h(l+b)
Total Surface Area = 2(lh+bh+lb)
Cube:
Volume = a³
Lateral surface / Curved Surface Area = 4a²
Total Surface Area = 6a²
Right Circular Cylinder:
Volume = πr²h
Lateral surface / Curved Surface Area = 2πrh
Total Surface Area = 2πr(h+r)
Right Circular Cone:
Volume = 1/3πr²h
Lateral surface / Curved Surface Area = πrl
Total Surface Area = πr(l+r)
Sphere:
Volume = 4/3πr³
Lateral surface / Curved Surface Area = 4πr²
Total Surface Area = 4πr²
Hemisphere:
Volume = 2/3πr³
Lateral surface / Curved Surface Area = 2πr²
Total Surface Area = 3πr²
Where, l = length
b = breadth
h = height
r = radius
a = area
