How to Find Triangular Pyramid Calculator?
The surface area of the triangular pyramid is defined as the amount of space enclosed within the boundary of a triangular pyramid. It is measured in square units. The formula to calculate the surface area of the triangular pyramid is given by
Surface area of the triangular pyramid = 1/2 (a × b) + 3/2(b × h)
Where 'a' is apothem length of the base triangle, 'b' is the base side of the triangle pyramid, and 'h' is the slant height of the triangular prism.
The volume of the triangular pyramid is the capacity of the triangular pyramid or the measure of the amount of space it occupies. It is measured in cubic units. The formula to calculate the volume of the triangular pyramid is given by
The volume of the triangular pyramid = 1/3 × Base Area of triangle × Height of pyramid
Note: Base area of a triangle = 1/2 × base width of triangle × base height of the triangle.
Solved Examples on Triangular Pyramid Calculator

Example1:
Find the surface area of a triangular pyramid whose apothem length of the base triangle is 5 units, base side of the triangle pyramid is 6 units, and slant height of the triangular prism is 8 units.
Solution:
Given: a = 5 units, b = 6 units, and h = 8 units
Surface Area of a Triangular Pyramid = 1/2 (a × b) + 3/2(b × h)
= 1/2(5 × 6) + 3/2(6 × 8)
= 15 + 72
= 87 square units

Example2:
Find the volume of a triangular pyramid with a base width of a triangle of 5 units, the base height of a triangle is 6 units, and the height of the pyramid is 9 units?
Solution:
The volume of a triangular pyramid = 1/3 × Base Area of triangle × Height of pyramid
= 1/3 × (1/2 × b × h) × a
= 1/3 × (1/2 × 5 × 6) × 9
= 5 × 9
= 45 cubic units.
Similarly, you can try the calculator to find the
 Find the surface area of the triangular pyramid if the apothem length = 6 units, base side = 8 units, and slant height = 14 units.
 Find the volume of a triangular pyramid if the base width of a triangle = 3 units, the base height of a triangle = 6 units, and height of the pyramid = 12 units
