Answer:
225
Explanation:
Well, we already know how many square inches each card is. 18. All we need to do is multiply that number by 150 because we need to make 150 cards. So:
18 x 150 = 2,700inches.
Now all we need to do is divide the number of inches by the amount each foot is. Each foot is 12 inches. So:
2,700 ÷ 12 = 225.
225 is your answer.
Hope this helps and have a nice day!
