edges: There are _____________ edges. The opposite edges are parallel and congruent.

vertices: The figure has _____________ vertices.

Prisms are three-dimensional figures. A prism has at least three faces that are rectangles. The top and bottom faces, called the bases, are congruent parallel polygons.

The figure above is a rectangular prism. In a rectangular prism, the bases are congruent rectangles. A rectangular prism has six rectangular faces, twelve edges, and eight vertices. Answer: The shape of the bag is a rectangular prism. – The figure has 6 faces. Each face appears to be a rectangle. – There are 12 edges. – The figure has 8 vertices.

Question 5. Mathematical PRACTICE Make Sense of Problems Gabriel is playing a board game. When it is his turn, he tosses a three-dimensional figure that has 6 square faces. What kind of figure is it? How many edges and vertices does it have? Answer: – The figure has 6 faces. A figure is one of the simplest shapes in three-dimensional space. All six faces of a figure are squares, a two-dimensional shape. – The figure has 12 edges. – The figure has 8 vertices. – From the above information, we can say that the above-given figure is the cube.
