I do this question yet get nothing close to the choices. Please help me and explain how I solve the areas.
1 answer:
The lid is 15 by 30 so the area is 15*30 = 450 square inches
The front panel and back panel are both 30*24 = 720 square inches. The left and right panels are 24*15 = 360 square inches
Add up the front, back, left and right panel areas and we get: 720+720+360+360 = 2160
The total gray area is 2160 square inches compared to the white lid which is 450 square inches. Subtract these two values: 2160-450 = 1710
Answer: Choice B) 1710 square inches
