Choose the measure you want to calculate and enter the required values in the triangular pyramid surface area calculator.
The surface area of a triangular pyramid calculator can be used to find the base length, volume, lateral surface area e.t.c. The formula for each property appears at the side.
A polyhedron having three triangular sides meeting at the apex on top and forming a triangular base at the bottom.
A triangular pyramid has 6 edges and 4 vertices. A triangular pyramid can be either regular (equilateral) or non-regular (isosceles).
Below are some properties of a pyramid. These can be calculated through the triangular pyramid calculator.
The surface area of a pyramid consists of the area of all the surfaces including the base.
The formula to calculate surface area is:
Where,
L = base length
w = base width
h = pyramid height
It is also a type of surface area measurement but it excludes the base of the pyramid.
Its formula is:
Where,
L = base length
w = base width
h = pyramid height
The total area occupied by a triangular pyramid in 3 dimensions (volume) is calculated by:
Volume = ( L x W x h )/ 3
In this equation:
L stands for length
W stands for width
h stands for height
The distance from the center of the base to the apex is called the height of the pyramid. It is calculated by:
Height = 3v/lw
V = volume
L = base length
w = base width
Example:
For the given set of information, calculate surface area.
Base length = 6 cm
Base width = 7cm
Height = 5cm
Solution:
Step 1: Write the formula.
Step 2: Put the values in the formula.
S.A = 6 * 7 + 6 √((7/2)2+52)+ 7√((6/2)2+52)
S.A = 6 * 7 + 36.62 + 40.8
S.A = 78.62 +40.8
S.A = 119.44
