Surface Area and Volume of a Cuboid

If the dimensions of the cuboid are: Length = l , Breadth = b and Height = h . Then:2018-12-29_16-43-54

i) Total surface area of the cuboid = 2(lb + bh + lh)

ii) Lateral surface are of the cuboid = 2(l+b)h

iii) Diagonal of the cuboid = \sqrt{l^2 + b^2 + h^2}

iv) Length of all 12 edges of the cuboid = 4(l + b + h)

v) Volume of a cuboid = lbh

If the length of each of the sides of the cube is l . Then

i) Total surface area of the cuboid = 6l^2

ii) Lateral surface are of the cuboid = 4l^2

iii) Diagonal of the cuboid = \sqrt{3} l

iv) Length of all 12 edges of the cuboid = 12l

v) Volume of cube = l^3
