The volume of a triangular prism tells us how much space it occupies. To find it, we first calculate the area of the triangular base and then multiply that by the prism's height (the distance between the two triangular faces). Remember the formula for the area of a triangle: $\frac{1}{2} \times base \times height$.
So, the volume of a triangular prism is calculated using the formula: $Volume = Area \ of \ Base \times Prism \ Height = (\frac{1}{2} \times base \times height) \times Prism \ Height$. Let's test your knowledge!
Match each term with its correct definition:
| Term | Definition |
|---|---|
| 1. Volume | A. The distance between the two triangular faces. |
| 2. Base (of a triangle) | B. The amount of space a 3D object occupies. |
| 3. Height (of a triangle) | C. The side of a triangle that is perpendicular to the height. |
| 4. Prism Height | D. The perpendicular distance from the base to the opposite vertex. |
| 5. Area of a Triangle | E. The measure of the surface enclosed by a triangle ($ rac{1}{2} \times base \times height$). |
(Match the numbers with the letters. Example: 1-B)
