Final Answer:
The volume of the triangular prism is

Step-by-step explanation:
To find the volume of a triangular prism, you can use the formula:
![\[ \text{Volume} = \text{Base Area} * \text{Height} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/p9f9goduyk4qje9j7cdv1bcn8eeg67c46p.png)
The triangular base area is given by the formula:
![\[ \text{Base Area} = (1)/(2) * \text{Base} * \text{Height} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/u4tgwl5d8pzy1sar9m6wjuvo96iu1l8pxu.png)
Given that the base has a length of 3 cm and a height of 4 cm:
![\[ \text{Base Area} = (1)/(2) * 3 \, \text{cm} * 4 \, \text{cm} = 6 \, \text{cm}^2 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/yosc6caaxqg1qk8d1wr5c4t5ezg0y2vc4s.png)
Now, multiply the base area by the length of the prism (12 cm):
![\[ \text{Volume} = 6 \, \text{cm}^2 * 12 \, \text{cm} = 36 \, \text{cm}^3 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/wwwdnf4lq1liz26hpa97o8kxcmzwd5l7ag.png)
Therefore, the volume of the triangular prism is
