To find the surface area of a rectangular prism, we can use the formula:

\[
\text{Surface Area} = 2(lw + lh + wh)
\]

where \( l \), \( w \), and \( h \) are the lengths of the edges of the prism. In this case, since each edge length measures 15.1 cm, we have \( l = w = h = 15.1 \) cm.

Now we can calculate:

\[
lw = 15.1 \times 15.1 = 228.01 \, \text{cm}^2
\]
\[
lh = 15.1 \times 15.1 = 228.01 \, \text{cm}^2
\]
\[
wh = 15.1 \times 15.1 = 228.01 \, \text{cm}^2
\]

Now we combine these values:

\[
lw + lh + wh = 228.01 + 228.01 + 228.01 = 684.03 \, \text{cm}^2
\]

Next, we multiply this sum by 2 to find the total surface area:

\[
\text{Surface Area} = 2 \times 684.03 = 1368.06 \, \text{cm}^2
\]

Therefore, the surface area of the rectangular prism is **1,368.06 cm²**.
