Hint: If students have trouble getting started on this problem, remind them that the diameter of a circle is the length of a line that connects two points on a circle and that crosses through the center of the circle. Students may choose to draw a line representing the diameter through the circles along one length and one width of the rectangle. This may help them visualize that the lengths of these lines is equal to the length and width of the rectangle.
Area = 122.88 sq cm
Since the diameter of each candy is 3.2 cm, the length of the box will be 3.2 cm × 4 candies or 12.8 cm, the width will be 3.2 cm × 3 candies or 9.6 cm. The area of the box will be 12.8 cm × 9.6 cm = 122.88 sq cm.
