Volume of a Triangular Prism
V = (½ × b × h) × L
Where: L = length of the prism, V = Volume, b = base of the triangle, h = height of the triangle
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: L = 7, b = 5, h = 10
Find: V (Volume)
- Formula: V = L·b·h/2
- Substitute the values: V = 10·5·7/2
- Result: V = 175
Answer: V = 175
