问题 A gift box has edges of 2 inches, 3 inches, and 7 inches. What is the surface area of the box, in square inches?______
选项
答案 82
解析 The correct answer is 82. To calculate the surface area, first calculate the area of each side of the box:
2 sides will have an area of 2x3 = 6 square inches.
2 sides will have an area of 2x7 = 14 square inches.
2 sides will have an area of 3x7 = 21 square inches.
Therefore, the surface area of the box is 2(6)+ 2(14)+ 2(21)= 82.
