Q5 of 76 Page 18

If V is the volume of a cuboid of dimensions x, y, z and A is its surface area, then A/V

Volume of a Cuboid = Length × Breadth × Height

Hence, Volume of a Cuboid V = xyz


Surface Area of a Cuboid = 2 × (Length × Breadth + Breadth × Height + Length × Height)


∴ Surface Area of a Cuboid A = 2 × (xy + yz + zx)
