To determine the number of quarts needed to clean 1500 cylinders, we first need to calculate the total surface area of all the cylinders. Once we have that total surface area, we can divide it by the surface area cleaned by one quart (7200 square inches) to find the number of quarts required. The formula to find the surface area of a cylinder is 2πrh + 2πr^2, where r is the radius and h is the height of the cylinder.

NO a cone is not a polyhedron as it has a curved surface. Similarly sphere and cylinders r 3D but not polyhedrons
It is possible for some cones A and cylinders B. But in general, the assertion is false.

A cuboid is a 3 dimensional object and 3 measures are required for the total surface area of a cuboid.
It depends on what you are cleaning. For general cleaning, a solution of water and vinegar works well. For tougher stains, a mixture of water and bleach can be effective. Always test any cleaning solution in a small, inconspicuous area before using it on a larger surface.
Surface tension must be reduced in order to clean a surface effectively. This can be achieved by using a cleaning agent or detergent that helps to break the surface tension, allowing the cleaning solution to spread and penetrate the surface for thorough cleaning.
To clean a surface, the surface tension of the cleaning agent must be lower than that of the surface. This allows the cleaning solution to spread out and penetrate the surface, lifting away dirt and grime. Lower surface tension helps the cleaning agent to break the bond between the surface and the contaminants, making it easier to clean.
A mixture of warm water and mild dish soap is a great tile floor cleaning solution for keeping your floors sparkling and spotless.
The best way to effectively clean surfaces using a cleaning scrub brush is to first wet the brush with water and apply a small amount of cleaning solution. Scrub the surface in a back-and-forth motion, applying gentle pressure. Rinse the brush frequently and continue scrubbing until the surface is clean. Finally, rinse the surface with water to remove any remaining cleaning solution.
The correct order for cleaning and sanitizing is: 1) remove debris and dirt from the surface, 2) wash the surface with soap and water, 3) rinse the surface with clean water, and 4) apply a sanitizing solution to kill germs and bacteria.
A contaminated surface needs to be dried after cleaning it because sometimes bacteria can grow and continue to thrive if a surface remains wet. Keeping the area dry after decontamination can greatly decrease the chances of it becoming contaminated again.
The surfactants in dish soap are the key ingredients that make it an effective cleaning solution. These surfactants help to reduce the surface tension of water, allowing it to penetrate and break down greasy or oily substances for easy removal.
