Option C is correct.
Step-by-step explanation:
Given:
Triangular prism
To find: Volume of the prism.
From figure,
Triangle of the base is a right angled triangle.
Legs of the triangle are 8 units and 6 units
Height of the Prism = 20 units
We know that,
Volume of the prism = Area of the Base × Height
Area of the Base = ![\frac{1}{2}\times Base\times Height=\frac{1}{2}\times8\times6=24\,units^2](/tpl/images/0297/7597/2dbd9.png)
⇒ Volume of the prism = 24 × 20 = 480 units³.
Therefore, Option C is correct.
