A cube with side length 3.14 cm contains 5 protons and 6 top quarks. A sphere with radius 10 cm shares the same center with the cube contains an additional 2 charm quarks and 17 electrons. A cylinder circumscribed around this sphere with a length of 30 m contains no net charge. A triangular prism around the cylinder with base area 20 m^2 and height 1 km contains 3 strange quarks, 88 leptons, 3 photons, 2 electrons, and 29 protons.
