There is no such thing as a 3D triangle.
A right angle triangle is a plane figure not a 3d one.
No because it is a 2 dimensional triangle having 2 equal sides and 2 equal base angles
An isosceles-triangle based prism.
There is none because a triangle is a 2D shape and volume measures 3D shapes ----------------------------------------------------------------- There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.
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?
1 Face (2D) 4 Faces (3D) 3 Sides 3 Points, and 2 Congruent sides.
least volume and most surface area is 3D triangle
A triangle is a 2 dimensional object, it cannot therefore have a volume (which is a property of 3D objects.However, if you meant area, then it's half the base length multiplied by the height.
It is an isosceles prism.
Well it depends on what kind of 3d shape it is. There is a formula to find the volume of each 3d shape. The main formula for volume is Bxh. (Big B multiplied by the height.) Bxh means the area of the base times the height.
Volume = area of cross-section*length
