We need to find the area of the package

10 times 12 times 1 is 120
 
the package is 120 in squared

each cube that holds one ring is 1 inch and there are 120 inches

so the jewelry store reveiced 120 rings.

the explaination.  to find how many rings are in  a package we need to find the volume of that package.  Then once we have that we need to find how many of the cubes can fit into that area.  

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats

4x 20 is 80 but if ther machine is broken then there is none you have to redo the test
