To find the volume of a pyramid, you can use the formula:
\[ \text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \]
In this case, the base area is calculated using the length and width of the pyramid:
\[ \text{Base Area} = \text{Length} \times \text{Width} = 10 , \text{cm} \times 18 , \text{cm} = 180 , \text{cm}^2 \]
Now, using the height of the pyramid, which is 12 cm:
\[ \text{Volume} = \frac{1}{3} \times 180 , \text{cm}^2 \times 12 , \text{cm} \]
Calculating this:
\[ \text{Volume} = \frac{1}{3} \times 2160 , \text{cm}^3 = 720 , \text{cm}^3 \]
Therefore, the correct response is 720 cm³.
