Q:

What is the difference between a cube and a cuboid?

A:

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 three-dimensional rectangle called?

    A:

    A three-dimensional rectangle is called a cuboid. A cuboid is defined as a closed box that is composed of six rectangular faces joined at right angles. The rectangles on opposite faces of the cuboid are identical to each other.

    How many sides does a cubiod have?

    A:

    A cuboid is a shape that looks similar to a box and has six flat sides. Cuboids also have only right angles, and all of the faces are rectangles.

  • Q:

    How many vertices does a cuboid have?

    A:

    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.
