# How To Calculate The Volume Of A Triangle?

## 3 Answers

There are a number of different answers to this question; I will give you the answers and then explain the differences.

- To calculate the area of a triangle the formula used is:
_ the base X the height
- On the other hand to calculate the volume of a pyramid (with a square base) the formula used is:
Area of the base X height X 1/3
- To calculate the volume of a pyramid (with a rectangular base) the formula used is:
Length of base X width of base X height X 1/3

So basically to explain these answers, you asked how to measure the VOLUME of a TRIANGLE; however in theory you don't measure volume of a triangle so I have given 3 different answers, which you can use depending on what you are required to do.

If the shape you are dealing with is a triangle (so a flat shape with three sides, definitely not 3 dimensional), then you will be looking for the area as opposed to the volume. Remember this, as you will be marked down in most math exams for confusing area and volume. For this sum you will use the first formula.

If, on the other hand, the shape is 3 dimensional (and so a pyramid rather than a triangle) then you will need to use either the second or third formula depending on whether the pyramid has a square or rectangular base. I, like many people, hated math when I was younger and my teacher spent 3 years telling me not to use the words interchangeably; I didn't really listen but when it came to exams I was confused because I hadn't listened!

A triangle is a plane figure that has no volume.

The area of a triangle is
area = bh/2, where b is the measure of the base, and h is the measure of the height (perpendicular to the base)

The volume of a pyramid is
volume = Bh/3, where B is the area of the base, and h is the measure of the height (perpendicular to the base)
