Tis making a case for a calculator it is a rectangular prism that will be 3.5 inches long by 1 inch wide by 10 inch high how much material will she need to find the surface area

In order to solve this problem you need to do length times width times height in order to do this you will do the length of the prism times the width of the prison times the height of the prison. So you would do 10 * 1 is 10 and then 10 * 3.5 is 35. So the volume of the rectangular prism is 35 cubic inches.
