The formula for a triangle-base pyramid (a form of tetrahedron) is
V = 1/3 Bh where B is the area of the triangular base
Find the area of the base by the formula B = 1/2 bh (height of that triangle), then multiply by 1/3 of the pyramid'sheight.
No. A 3D triangle would be a triangular based pyramid.
V = base area x height divided by 3
a triangle- based pyramid has 4 faces
A triangular-based pyramid has six edges: three in the base triangle and three from there to the apex.
5 faces 8 edges 5 corners (vertexes) * * * * * Wrong! The answer given above is for a SQUARE based pyramid. A triangle based pyramid, or a tetrahedron, has 4 faces, 6 edges and 4 corners (vertices).
we dont know
Volume of a pyramid = 1/3*base area*height in cubic units
The answer depends on the what characteristic of the pyramid you want the formula for: its surface area, its volume or something else.
A TRIANGLE based PYRAMID is called a tetrahedron.
No. A 3D triangle would be a triangular based pyramid.
Wouldn't a circle-based pyramid look a lot like a cone ? If so, you could probably use the formula for the volume of a cone and get away with it.
A triangle is a 2D shape, so as such it has no volume. (Since it is a length and a width, but has no depth). The equivalent of a triangle in 3D is a triangular based pyramid, which clearly does have a volume. You may have meant "area" rather than volume?
a triangular based pyramid
V = base area x height divided by 3
a triangle- based pyramid has 4 faces
Vol = 1/3 * base area x vertical height for any pyramid (or cone).
Volume = Area of the base X height of prism. This formula works for all prisms, not just triangular prisms. Area of a triangle = height of triangle X 1/2 X base of triangle.
