Question

Lauren bought a rectangular box that is 6 inches long, 10 inches wide and 4 inches high. she wants to cover it in fabric. the fabric costs $0.25 per square inch. How much will the fabric costs?

Answer 1

First you'll need to find the area of each side and then add those areas together. 2(6x10)+2(4x6)+2(4x10)= 120+48+80=248 
then you multiply the total area by .25 and get 62. It will cost $62.
