The volume \( V \) of a rectangular pyramid can be calculated using the formula:

\[
V = \frac{1}{3} \times \text{Base Area} \times \text{Height}
\]

In this case, the base is a rectangle with a length of 12 m and a width of 12 m. Therefore, the area of the base \( A \) is:

\[
A = \text{Length} \times \text{Width} = 12 \, \text{m} \times 12 \, \text{m} = 144 \, \text{m}^{2}
\]

The height of the pyramid is given as 10 m.

Now, we can plug these values into the volume formula:

\[
V = \frac{1}{3} \times 144 \, \text{m}^{2} \times 10 \, \text{m}
\]

\[
V = \frac{1}{3} \times 1440 \, \text{m}^{3}
\]

\[
V = 480 \, \text{m}^{3}
\]

Thus, the volume of the rectangular pyramid is **480 m³**.
