What 3D shape has all the faces the same shape and flat?
a cube * * * * * A cube is only one example. Any one of the five Platonic solids - tetrahedron, cube or hexahedron, octahedron, dodecahedron or icosahedron - are made up from congruent plane faces.
How many solids does a tetrahedron have?
One: a tetrahedron is a single solid.
Does a tetrahedron have any right angles?
No. A right angle would be 90 degrees; a tetrahedron is composed of four equilateral triangles, which by definition have equal angles of 60 degrees apiece.* * * * *Wrong!A tetrahedron is a solid shape enclosed by any four triangles. Only a regular tetrahedron that requires equilateral triangles. So an ordinary tetrahedron can have right angles - up to 3 of them at one vertex.
What shape has one triangular base and three triangular lateral faces?
A tetrahedron.
What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.

How many solids does a tetrahedron have?
One: a tetrahedron is a single solid.
What are the symmetries of a cube and a regular tetrahedron?
24 for the cube (any one of 6 faces on the table, and then any one of 3 facing you), 12 for the tetrahedron (4 down and 3 facing).
What 3dimensional shape has 7 faces?
A pentagonal prism, a hexagonal pyramid, a cube with one vertex (corner) cut off, a tetrahedron with three vertices cut off - these are some of the possibilities.
Does a tetrahedron have any right angles?
No. A right angle would be 90 degrees; a tetrahedron is composed of four equilateral triangles, which by definition have equal angles of 60 degrees apiece.* * * * *Wrong!A tetrahedron is a solid shape enclosed by any four triangles. Only a regular tetrahedron that requires equilateral triangles. So an ordinary tetrahedron can have right angles - up to 3 of them at one vertex.
What 3d shape has more than one vertex?
Possibly a cone? No, A cone is one of the few solid objects with one vertex. A pyramid (which includes a tetrahedron) has 4 or more. A prism (which includes a cube) has 6 or more (but even numbers only). Other regular solids are octahedron (6 vertices), dodecahedron (20), icosahedron (12).
What is a substance that keeps its shape because its particles cant flow freely?
A solid is a substance that keeps its shape because its particles cannot flow freely. The particles in a solid are tightly packed together and vibrate in place, giving the solid a fixed shape and volume.
What 3D shape has 6 edges 4 faces 4 vertices?
Tetrahedron - basic to theory of chemical bonds and one of the classic Platonic solid shapes
What shape has four flat faces and each one is triangular?
A tetrahedron.
Will the shape of an ice cube affect the rate at which it melts?
A cube can only have one shape "cubic" - (someone has asked you a trick question). However, certainly the rate at which a piece of solid ice melts IS affect by its shape, the greater the surface area of the piece of ice, the faster it will melt.
What shape has one triangular base and three triangular lateral faces?
A tetrahedron.
Solid figure with 6 faces?
Cube * * * * * A cube is a very special case. A more general one would be a rectangular prism (shape of a brick). Even more would be a rhombic hexahedron.
