Explanation:
The question has missing details, as the diagram of the prism is not shown.
However, I'll solve using a general rule.
The volume of a triangular prism is:
![Volume = (1)/(2)* b * h * l](https://img.qammunity.org/2022/formulas/mathematics/high-school/3xcj9fzea6d5r0drroxprplarq2wt8wypw.png)
Where
![b = base](https://img.qammunity.org/2022/formulas/mathematics/high-school/ns91b0mqfyqmhwigefcoijgjcrtijoorx7.png)
![h = height](https://img.qammunity.org/2022/formulas/physics/college/ql7f1ndu1ha58ej70sjl2iihuqovj65hil.png)
![l = length](https://img.qammunity.org/2022/formulas/mathematics/high-school/qnorqf0okifuo1vakdo5vnziw6aqdnjraz.png)
Take for instance:
![b = 20cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/6tsugbxpr5mg9tubkedq4q9m8yn10znzna.png)
![h = 10cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/wjqiysrryf751ha0gva280z765fx226xvr.png)
![l = 5cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/hm4eiaew7a5la15ik4xoq7isxqwnvyemx4.png)
The volume is:
![Volume = (1)/(2) * 20cm * 10cm * 5cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/hok7526xhcy9ctun524lw334ta2w8x5jzb.png)
![Volume = 10cm * 10cm * 5cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/6sqb0ekiuy2stn910ywbfgmfyqxawn7h3c.png)
![Volume = 500cm^3](https://img.qammunity.org/2022/formulas/mathematics/high-school/ah2o1sjj4716gt5rk7ztcl1t741baumzdi.png)
Another instance (see attachment).
From the attachment:
![b = 4.5cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/bcqzqsbfsbm41afhxu80puhfylbnrqwo0m.png)
![h = 5cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/rt8wivdic5xqeexvn1kyd83lxmyhbheeg6.png)
![l = 8cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/rgdgr7uld0wbtubd9p04loiyd2iqj99qdd.png)
The volume is:
![Volume = (1)/(2) * 4.5cm * 5cm * 8cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/k2t16tjtrxwc2xeymji84hl4thu0sfz2t7.png)
![Volume = 2.25cm * 5cm * 8cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/7pvh3bc7pmu9v1rpnthew012t032o8m6f7.png)
![Volume = 90cm^3](https://img.qammunity.org/2022/formulas/mathematics/high-school/gw0ie07j1xhk2ko87k5yd19q5glyk4thyw.png)
