To find the equation that represents the problem, let's define the variables and break down the information given.

1. **Total number of floors**: 18
2. **Total number of offices in the building**: 396
3. **Let \( f \)** represent the number of offices on each floor.

Since each floor has the same number of offices, the total number of offices can be calculated by multiplying the number of floors by the number of offices per floor. This relationship can be expressed with the equation:

\[
\text{Total Offices} = \text{Number of Floors} \times \text{Offices per Floor}
\]

Substituting the values into the equation gives us:

\[
396 = 18f
\]

To solve for \( f \) (the number of offices on each floor), we can rearrange it to:

\[
18f = 396
\]

This matches option **B**.

Therefore, the correct equation that can be used to find \( f \) is:

**Answer: B \( 18f = 396 \)**.

To find the equation for the number of offices on each floor (\( f \)) of a building with 18 floors and a total of 396 offices, we use the relationship:

\[
\text{Total Offices} = \text{Number of Floors} \times \text{Offices per Floor}
\]

This gives:

\[
396 = 18f
\]

Rearranging gives:

\[
18f = 396
\]

Thus, the correct choice is **B \( 18f = 396 \)**.
