Volume of a Triangular Prism
Finding the volume of a triangular prism is almost the same as finding the volume of a rectangular prism.
The difference is that now the base is a triangle and you'll remember the formula for finding the area of a triangle is:
A =1/2 x base x height
A = 1/2bh
For a triangular prism first find the area of the base, then multiply it by the length.
The area of the base will be:
A = 1/2bh =1/2 x4x6 = 12cm2
To find the volume multiply the area of the base times the length.
V = base area x length
V = 12 x 12 = 144cm3
So the formula for finding the volume of a triangular prism is:
Volume = Area of base x length = (1/2 x b x h x l)
