Answer:

The formula for calculating the surface area of a cuboid is as follows.

Surface Area of Cuboid = 2lw + 2lh + 2hw

Where,

  • l = Length = 20cm
  • w = Width = 5cm
  • h = Height = 10cm

Therefore,

Surface Area of Cuboid = (2 x 20 x 5) + (2 x 20 x 10) + (2 x 10 x 5)

                                         = 200 + 400 + 100

                                         = 700 [tex]cm^{2}[/tex]
