To find the surface area of a right rectangular prism (also known as a cuboid), you 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. Since all edge lengths are equal in this case (the prism is a cube), we have:

  • \( l = 15.10 , \text{cm} \)
  • \( w = 15.10 , \text{cm} \)
  • \( h = 15.10 , \text{cm} \)

Substituting these values into the surface area formula gives:

\[ \text{Surface Area} = 2(15.10 \times 15.10 + 15.10 \times 15.10 + 15.10 \times 15.10) \]

Calculating \( 15.10 \times 15.10 \):

\[ 15.10 \times 15.10 = 228.01 , \text{cm}^2 \]

Now substituting this value back into the formula:

\[ \text{Surface Area} = 2(228.01 + 228.01 + 228.01) = 2(684.03) = 1368.06 , \text{cm}^2 \]

Thus, the surface area of the right rectangular prism is:

1,368.06 cm² (or 1,368.06 cm2).
