The surface area of the given cuboid is 22 cm²
Surface area of Solid shapes
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
