To calculate the surface area of a cuboid, we use the formula:

\[
\text{Surface Area} = 2(\text{Length} \times \text{Width} + \text{Length} \times \text{Height} + \text{Width} \times \text{Height})
\]

Given:
- Length \( L = 20 \, \text{cm} \)
- Width \( W = 11 \, \text{cm} \)
- Height \( H = 13 \, \text{cm} \)

Now substitute the values into the formula:

\[
\text{Surface Area} = 2(20 \times 11 + 20 \times 13 + 11 \times 13)
\]
\[
= 2(220 + 260 + 143)
\]
\[
= 2(623)
\]
\[
= 1246 \, \text{cm}^2
\]

Thus, the surface area of the cuboid is \( 1246 \, \text{cm}^2 \).
