Volume of a TRIANGULAR PRISM
FORMULA SHEET
CALCULATOR
The formula for volume of a TRIANGULAR PRISM is V=(area of the base) x (height of prism)
(3 points)
Part 1: Find the area of one TRIANGLE BASE of the prism: Area =
in2
Part 2: What is the height of the prism? The height connects the 2 bases.
in
Part 3: Find the volume of the triangular prism using V=(area of the base) x (height of prism) =
in3
Volume = (Area of base) x Height
Part 1: Find the area of one triangular base of the prism. Let's say the base is a right triangle with base b and height h. The formula for the area of a right triangle is A = 0.5 x b x h.
Part 2: Find the height of the prism, which is the perpendicular distance between the two triangular bases.
Part 3: Substitute the area of the base and the height into the formula for volume to calculate the volume of the triangular prism.
