10.) We need to get the total area of the box.
4 rectangles : length = 4cm ; width = 3 cm
2 squares : side lengths = 3cm
Area of rectangle = 4cm * 3cm = 12 cm² * 4 = 48 cm²
Area of square = (3cm)² = 9cm² * 2 = 18cm²
48cm² + 18cm² = 66cm²
Area of paper = 15cm * 20cm = 300 cm²
wasted area = 300 cm² - 66cm² = 234 cm²
