To find the volume of a rectangular pyramid, you can use the formula:

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

For a square pyramid with a side length \( s = 12 \) meters:

  1. Calculate the base area: \[ \text{Base Area} = s^2 = 12^2 = 144 , \text{m}^2 \]

  2. Use the height \( h = 10 \) meters in the volume formula: \[ V = \frac{1}{3} \times 144 , \text{m}^2 \times 10 , \text{m} \] \[ V = \frac{1}{3} \times 1440 , \text{m}^3 \] \[ V = 480 , \text{m}^3 \]

Therefore, the volume of the rectangular pyramid is 480 m³.
