Q:A:### Quick Answer

**A cube is a six-faced, three-dimensional figure composed of square-shaped faces of the same size that meet at 90-degree angles, whereas a cuboid is a box-shaped object made of six faces that all meet at 90-degree angles.** A cuboid shape can also be a cube if all sides are the same length, but not all cuboids are cubes. Cubes and cuboids contain eight vertices and 12 edges.

A cuboid shape has three pairs of rectangular faces placed opposite of each other. Opposite faces are exactly the same. Two of the six faces of a cuboid shape can be squares. Cuboids are also called right prisms, rectangular parallelepipeds and rectangular boxes. The volume of a cuboid is described by the formula "a*b*c" where "a," "b" and "c" are the lengths of each side. The surface area of a cuboid is "2(a*b + b*c + c*a)" where each letter is a side length.

A cube is a Platonic solid also known as a regular hexahedron. The surface area of a cube is delineated by the formula "6*a^2," where "a" is the length of a side. The volume of a cube is "a^3."

Examples of cuboid shapes include boxes, doors and mattresses. Cuboids can be flattened into six two-dimensional rectangles.

## What is a rectangular prism?

A:A rectangular prism is a three-dimensional object that has six faces that are all rectangles. On a rectangular prism, opposite faces are both equal and parallel. Rectangular prisms also have the same cross section along their lengths.

## How many vertices does a cuboid have?

A:

Full Answer >**A cuboid always has eight vertices.**A cuboid is a three-dimensional shape that is similar to a cube in that it has six faces that are all at 90-degree angles to each other, but at least two of the faces on a cuboid are rectangles, not squares.Filed Under: - Q:

A:

Full Answer >**A pentagonal pyramid is characterized by six faces, six vertices and 10 edges.**This three-dimensional polyhedron is a type of pyramid containing five triangular lateral faces and one pentagonal face, which is the base of the pyramid.Filed Under:
