CUBOID
Let length = l, breadth = b and height = h units. Then,
1. Volume = (l x b x h) cubic units.
2. Surface area = 2 (lb + bh + lh) sq. units.
3. Diagonal = √l^{2} X b^{2} X h^{2} units,

CUBE
Let each edge of a cube be of length a, Then,
1. Volume = a^{3} cubic units.
2. Surface area = 6a^{2} sq. units.
3. Diagonal = √3 a units,

CYLINDER
Let radius of base = r and Height (or length) = h. Then,
