Known and Unknown Facts about Cubes

, , Leave a comment

A three dimensional object with whose sides measure the same is defined as a cube. The height width and depth of a cube are all equal and the sides are at right angle to one another.

Here are some known and unknown facts about this mathematical 3D figure.

  • A Cube has 6 faces or sides, 8 vertices and 12 edges.

  • Any object that is shaped like a cube is referred to as cubic in shape.

  • Cuboid is a broader term that refers to any convex polyhedron that has six quadrilateral surfaces.

  • Among all cuboids of a particular surface area, the cube has the largest volume.

  • The dice that we play with is cubical in shape and has 6 numbers or dots, with a single number featured on each side.

  • In 1974 Erno Rubik created the first Rubik Cube which is a 3D combination puzzle and it took him one month to solve it.

  • In 1982 Ronald Brinkmann first set a world record by solving the Rubik Cube in 19 seconds which was later broken and reduced to 9 seconds.

  • A Rubik’s cube has standard colours of red, green, yellow, orange, blue and white. Purple is not a traditional colour of the Rubik’s cube.

  • The Rubik’s cube can be solved using an algorithm. Simply twisting and turning and creating different combinations would only lead you to give up at some point if you don’t have the algorithm.

  • The algorithm that uses the least number of positions and moves to solve the Rubik’s cube puzzle is referred to as the ‘˜God’s number’.

  • The International Rubik Foundation was created by Erno Rubik to support special and talented young engineers and also industrial designers.

  • A Rubik’s cube has over 43 quintillion possible combinations or colour arrangements.

  • A cube made out of paper opens up along its edges to get 11 nets of cubes.

  • Drinking straws connected with tripods of florist wire, toothpicks, chopsticks, wires joined through soldering can be formed into cubes.

  • A cube has 9 symmetry planes, 3 of them are parallel to side squares while six more pass through the 2 body diagonals and opposite edges.

  • When the corners of a cube are cut, a separate body is formed comprising of eight equilateral triangles and 6 octagons.

  • The diagonals of a cube join to form a tetrahedron.

  • A cube can be divided into three pyramids which have equal volumes.

  • A cubical building was built in Iceland that was dark blue in colour with a layer of water over it and a round water pond inside that served as a screen for the movie based on Iceland in the bird’s eye view.

  • In Germany, the Expo 2000 in Hanover exhibited a giant cube.

  • The surface area of a cube can be calculated with the formula 6a2 where ‘a’ is equal to the measurement of the side of the cube. The formula for the volume measures of a cube is a3.

  • Any number that has the power of 3 is referred to as cube because the volume of the cube is calculated in the third powers.

In the four dimensional Euclidean space has a special name called the tesseract or hypercube.
