Surface Area and Volume of a Cuboid

If the dimensions of the cuboid are: Length $= l$, Breadth $= b$ and Height = $h$. Then:

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 $= lbh$

Surface Area and Volume of a Cube

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 $= l^3$
