- what does a 4d shape look like(58 votes)
- Interesting question!

An example of a 4d figure is a tesseract, which is a 4d extension of a cube. This can be constructed by drawing two cubes of the same size, then joining each corner (or vertex) of the first cube with the corresponding corner of the second cube (using a line segment to join them).(68 votes)

- For example, to draw a representation of a 4d cube (called a tesseract):

1) Draw two 3d cubes, oriented in the same way.

2) Draw a line segment connecting each vertex of one cube to the corresponding vertex of the other cube.

The link https://mathworld.wolfram.com/Tesseract.html shows a picture of a tesseract.

- Honestly, who invented math?!(8 votes)
- The Greek mathematicians are credited with developing mathematics. Several topics from different parts of the world were contributed at the same time by numerous mathematicians. So, nobody is called an inventor of mathematics. But the father of mathematics, Archimedes, is widely regarded(4 votes)
