A triangular prism
Pyramid
There is no 3-d shape for only hexagons. They have to be mixed with pentagons or squares.
3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.
A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.
A triangular prism
There can be no closed 3D shape with only one square and 3 triangles.
Pyramid
square based prism?
There is no 3-d shape for only hexagons. They have to be mixed with pentagons or squares.
Triangular prism
Differences: Squares have 4 sides / equilateral triangles have 3 sides. Squares have 90 degree angles / equilateral triangles have 60 degree angles. Squares have 2 diagonals / equilateral triangles have none Similarities: All sides of the shape are congruent All angles of the shape are congruent
There is no 3D shape with 6 faces: 4 rectangles and 2 triangles. See the link for all forms of hexahedra.
No because squares have 4 sides whereas triangles have 3 sides
A triangular prism.
A 3-d shape with 6 equal faces is a cube. It has 6 squares as it's faces. A 3-d shape with 6 equal faces and only 2 squares is a rectangular prism. It has 2 squares and 4 other rectangles (squares are rectangles too) as it's faces.
3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.
