From the question,

We are to calculate the surface area of the given cuboid.

The formula for calculating the surface area of a cuboid is

[tex]S.A = 2lw + 2lh + 2hw[/tex]

Where,

[tex]l[/tex] is the length

[tex]w[/tex] is the width

and [tex]h[/tex] is the height

From the given diagram

[tex]l = 3cm[/tex]

[tex]w = 2cm[/tex]

and [tex]h = 1cm[/tex]

Putting the parameters into the formula, we get

[tex]S.A = 2(3\times 2) + 2(3\times 1) + 2(1\times 2)[/tex]

This becomes

[tex]S.A = 2(6) + 2(3) + 2(2)[/tex]

[tex]S.A = 12 + 6 + 4[/tex]

S.A = 22 cm²

Hence, the surface area of the given cuboid is 22 cm²
