To calculate the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6 \times ( \text{edge length} )^2 \]
Given the edge length of the cube is 16.35 mm, we can substitute this value into the formula:
\[ \text{Surface Area} = 6 \times (16.35 , \text{mm})^2 \]
Calculating \( (16.35 , \text{mm})^2 \):
\[ (16.35)^2 = 267.6225 , \text{mm}^2 \]
Now multiply by 6:
\[ \text{Surface Area} = 6 \times 267.6225 , \text{mm}^2 = 1605.735 , \text{mm}^2 \]
Rounding this to the nearest whole number gives:
\[ \text{Surface Area} \approx 1606 , \text{mm}^2 \]
However, the closest option you provided is \( 1,604 , \text{mm}^2 \).
So, the final answer is:
1,604 mm².
