# How do you find the volume of a pyramid with an equilateral triangle base?

## How do you find the volume of a pyramid with an equilateral triangle base?

What Is the Volume of a Regular Triangular Pyramid? The volume of a regular triangular pyramid can be calculated given the edge of triangular faces. The formula for regular triangular pyramid volume is given as, Volume = a3/6√2, where ‘a’ is the edge of the triangular (equilateral) faces.

## What is the formula for volume of a triangular based pyramid?

The volume of a triangular pyramid can be found using the formula V = 1/3AH where A = area of the triangle base, and H = height of the pyramid or the distance from the pyramid’s base to the apex.

What is an equilateral triangular pyramid?

A triangle-based pyramid has four triangular sides. The base can be any shape or size of triangle but usually it is an equilateral triangle (all sides are the same). This means the three sides of the pyramid are the same size as each other and the pyramid looks the same if you rotate it.

### What is the volume of a equilateral triangle?

The volume of an equilateral triangular prism can be easily found out by using the formula, Volume = (√3/4)a2 × h, where,’a’ is side length and ‘h’ is the height of the equilateral triangular prism.

### Is a pyramid made of equilateral triangles?

When the base is a triangle, the pyramid is a triangular pyramid. It is also known as a tetrahedron since, including the base, it has four faces. When these faces are equilateral triangles, it is a square pyramid, having a square as its base. The pyramids most commonly encountered are “regular” pyramids.

What is volume of a triangle?

The area of a triangle is A=12bh. Essentially, to find to the volume of the triangular prism, you are multiplying the area of the triangle times the length or depth. So, the formula for the volume of a triangular prism would be V=12bhl.

## How to calculate the volume of a pyramid with an equilateral triangle?

Volume of a pyramid with equilateral triangle as base. The elementary approach is best, the height of the pyramid intersects the base at the centroid of the base, so use the 2:1 ratio and Pythagoras to figure out one of the catheti of the right triangle with the slant edge as its hypotenuse. This allows you to determine the height…

## How tall is the base of a pyramid?

The base of a right pyramid is an equilateral triangle of side 4cm each. Each slant edge is 5cm long. The volume of pyramid is (a) But this may be wrong because volume is 1 3 × base × height and in the solution, slant edge is used in place of height.

How big is the area of an equilateral triangle?

@Kiran An equilateral triangle’s area is 3 4 s 2 , with s = the triangle’s side, and then he center of the triangle is of length s 3 , so taking the straight triangle formed by the pyramid’s apex, the center of the base triangle and one of the vertices, the height is, by Pythagoras: Thanks for contributing an answer to Mathematics Stack Exchange!

### Why are the Pyramids of Egypt called square pyramids?

When you think about a Pyramid, the first thing that comes to your mind is the Great Pyramids of Egypt. If you observe the shape of the Great Pyramid of Egypt, then you will notice that the pyramid has a base, that is square shaped. Hence, those pyramids are called Square Pyramid.
