**A Triangular Pyramid And Its Net Are Shown** – A triangular pyramid is a three-dimensional solid – a polyhedron – with a triangular base and triangular faces that meet at the top of the pyramid.

Just as you have a triangular pyramid, you can have a square pyramid, a pentagonal pyramid, etc.

## A Triangular Pyramid And Its Net Are Shown

For example, the Great Pyramids of Egypt at Giza are a square pyramid because the base (bottom) is square. A triangular pyramid is a pyramid with a triangular base.

A pyramid with an equilateral triangular base is a regular triangular pyramid. If an isosceles or isosceles triangle forms the base, the pyramid is an irregular triangular pyramid.

There is no rule that requires the base of a triangular pyramid to be an equilateral triangle, although building isosceles or isosceles triangular pyramids is more difficult than building an equilateral triangular pyramid.

The lateral surface, LSA, does not include the base of our pyramid. The area of the pyramid, SA, includes the base.

The surface area of a triangular pyramid with three adjacent and visible faces is the area of the three triangular faces plus the area of the triangular base.

#### Perimeter Of A Triangle: Definition & Example

The formula for calculating the floor area includes the width of the base, the perimeter of the base and the height of any side slope.

SA=BaseArea+12(perimeter×SlantHeight)SA=Base Area+frac(perimetertimes Slant Height) S A = B a se A re a + 2 1 (P er im e t er × Sl an t He i g h t )

This formula works by adding the base area to the area of all three curved surfaces. The circumference gives you the sum of the three bases. As if you had a large rectangle, multiply the sum by the height of the triangular pyramid, then take half the area of the three triangles.

Since all three sides are 10 cubits, the base of the pyramid is an equilateral triangle. To find the area of the base triangle, use this formula for the area of the equilateral triangle with side a

Now we have found the location of the base. We know that the perimeter of the base is 30 cubits (the three sides are 10 cubits each) and the front height 14 cubits.

You may need to take time to go through all of these, find the location of the base, look around, add everything.

To find the side area – the lateral surface area (LSA) – you need to do a lot less work:

LSA=12(perimeter×slope height)LSA=frac(perimeter times slope height)

These formulas only work for regular pyramids. If you have an irregular triangular pyramid, calculate the area of each of the four faces separately (the three inclined faces and the base) and add them together.

Volume is the amount of space a 3D object occupies, so in a triangular pyramid we find how many rooms it has inside. It is always measured in cubic units. Although the pyramid is quickly reduced to the highest level, the calculation is not difficult.

In the formula for the volume of a triangular pyramid, a is the width of the base and h is the height from the base to the apex.

For a pyramid base of 10 cubits, the slope is 13.0767. We know the area from our previous calculations, so we can plug in known numbers to find the volume in cubic meters:

### What Is A Pyramid Scheme? How Does It Work?

Note that we do not have an exact decimal answer because we are multiplying the fraction, so we have an approximate value.
