The number on sandpaper, or the grit, represents the number of abrasive particles per inch of sandpaper. The lower the grit, the rougher the sandpaper. The grit can range anywhere from 40 (very course), to 600 (very fine.)
The numbers on the back of sandpaper refer to the grit size, which indicates the coarseness or fineness of the abrasive particles on the paper. Lower numbers indicate coarser grits, suitable for heavy material removal, while higher numbers denote finer grits, ideal for smoother finishes.

To sharpen a knife using sandpaper, start by securing the sandpaper on a flat surface. Then, hold the knife at a 20-degree angle and slide it back and forth across the sandpaper in a smooth motion. Repeat this process on both sides of the blade until the knife is sharp. Remember to use a fine-grit sandpaper for best results.
Sandpaper gets warmer when rubbed against wood due to friction.
The wood changes color
The Chinese were the first to use sandpaper, dating back to the 13th century. They would glue crushed shells and sand to parchment to create an abrasive surface for smoothing wood.

After primer is applied, use 220-grit sandpaper for a smooth surface. Change sandpaper frequently, and wipe the primer down to remove dust. Vacuum the floor to remove the dust, and keep it from flying back up onto the primered surface.
Rubbing sandpaper back and forth quickly over a piece of wood will smooth the surface of the wood by removing uneven spots, rough patches, and splinters. It will also create friction that generates heat, which can burn the wood if excessive pressure is applied or if the sandpaper grit is too rough.
If you want to add numbers in different bases, in this case decimal and binary, or do any other calculation that involves different bases for that matter, you have to convert all numbers to a single system first - for example, all to decimal. Then you can do the operation. It is really up to you in what base you represent the final answer. In this example, you can convert back to binary, for example.
You can make a back scratcher at home from a solid piece of wood. You can shape the back scratcher to your liking by using daily tools and then sand it down with sandpaper. You can also paint or stain it to make it look better.
Calculate the percentage for the numbers and then put the variables back in the answer.For example,20% of 36y = (20% of 36)*y = 7.2*yor25% of 36/y = (25% of 36)/y = 9/y.
