The grit on garnet paper is made up of sharp, angular particles that scratch and abrade the material being sanded. As the paper is used, these sharp edges break down and expose fresh cutting edges, maintaining its abrasive effectiveness.
Coins have smooth edges to make them easy to stack and handle. Rough edges, also known as reeded edges, are added to coins as a security feature to prevent counterfeiting by making it difficult to file down or alter the edges of the coin.
Knives and scissors have edges to cut things, but nails do not have sharp edges, they have points to penetrate hard surfaces.
Crater edges are called rims. They are the raised edges that surround the depression created by an impact from a meteorite or other object striking the surface of a planet or moon.
Sandpaper is made with corundum because it is extremely hard (9 on the Moh's Scale of Hardness) compared to just about anything else, except diamond (which top the scale at 10). This "hardness" is basically the factor which determines what happens when scraped against another material. If the corundum in the sandpaper is harder than whatever you are rubbing it against, then it will scratch the surface. If the sandpaper is used on something harder than corundum, the sandpaper will not be able to leave abrasions. Corundum is used because there are very few materials which it will fail to scratch.
Rocks that have sharp edges are often formed from the cooling and solidification of magma. These cooling processes can occur quickly, resulting in the formation of sharp edges and angular shapes. Some examples of rocks that may have sharp edges include basalt, obsidian, and flint.

k but how is it cylinder,my brother is in 7th class and im in 9th so i forgot the chapter,so can u explain me?

A tetrahedron is a triangular based pyramid that has 4 equilateral triangle faces, 6 edges and 4 vertices.
24 edges.24 edges.24 edges.24 edges.
A pentagonal prism has 15 edges. 10 of these are base edges and then 5 lateral edges. Formula : A prism with a n-sided polygons at each end will have 3n edges.
a sphere has no edges. a circle has no edges.
Any shape with straight edges can have perpendicular edges.
16 edges- the edges of the base, and the edges leading to the point of the pyramid.
Cubes are 3 dimensional figures and are equal on all edges. Therefore if one face is not a rectangle, then no face is a rectangle. Basically no.
A cube is a 3 dimensional shape with 6 faces, 12 edges and 8 vertices whereas a quadrilateral is a 2 dimensional shape with 4 sides.
A cube has twelve edges.
