Puzzle sunday (25)

Today's puzzle is a visualisation exercise. It's something to do with your mind's eye.

Imagine you don't have materials, only what's in your environment. Now how would you make a cylinder, a cube and a tetrahedron that each one has a volume of 1 deciliter? You may use 4 imaginary tools. What steps are necessary?

How does your imagination work? Are you like Berkeley who thinks you can imagine concise shapes? or like Locke who says that one could visually imagine a triangle neither equilateral, nor isosceles, nor scalene but somehow all and none of these at once?

Do you solve this with words, with images, with ideas, with colour?
