A marble is a small spherical toy often made from glass clay steel plastic or agate these balls vary in size. The total cost to install granite is 3 000 5 000 for an average size counter surface area of 40 sq ft. Give the students the opportunity to devise an improvement before suggesting the method illustrated above.
