1. Cube A cube[1] is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex[1]three-dimensionalsquarefacetsvertex Surface Area = 6a 2 Volume = a 3 When sliced the shape is a square.

2. sphere A sphere (from Greek σφα ῖ ρα—sphaira, "globe, ball") is a perfectly round geometrical object in three- dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point. This distance r is known as the radius of the sphereGreekgeometricalthree- dimensional spaceballcirclesymmetricalradius

3. Light changes speed as it moves from one medium to another (for example, from air into the glass of the prism). This speed change causes the light to be refracted and to enter the new medium at a different angle (Huygens principle). The degree of bending of the light's path depends on the angle that the incident beam of light makes with the surface, and on the ratio between the refractive indices of the two media (Snell's law). The refractive index of many materials (such as glass) varies with the wavelength or color of the light used, a phenomenon known as dispersion. This causes light of different colors to bespeedrefractedHuygens principleincidentrefractive indicesSnell's lawwavelengthdispersion PRISM

4. For a given volume, the cylinder with the smallest surface area has h = 2r. For a given surface area, the cylinder with the largest volume has h = 2r, i.e. the cylinder fits in a cube (height = diameter.) CYLINDER

6. A cone is a three-dimensional geometric shape that tapers smoothly from a flat, usually circular base to a point called the apex or vertex. More precisely, it is the solid figure bounded by a plane base and the surface (called the lateral surface) formed by the locus of all straight line segments joining the apex to the perimeter of the base. The term "cone" sometimes refers just to the surface of this solid figure, or just to the lateral surface.three-dimensionalgeometric shapeplanelocusperimeter CONE

7. A pyramid (from Greek "πυραμίς" – pyramis[1]) is a structure where the outer surfaces are triangular and converge at a point. The base of a pyramid can be trilateral, quadrilateral, or any polygon shape, meaning that a pyramid has at least three triangular surfaces (at least four faces including the base). The square pyramid, with square base and four triangular outer surfaces, is aGreek[1]structurefaces square pyramid PYRMID
