You can put this solution on YOUR website! First off that's one wired looking box of matches...lol
It's best to draw a picture diagram to help you see how many sides there are and which measurements are on each side
You should have: two (4 x 2.5) , two (4 x 15) , and two (15 x 2.5) sides
Finding the sum of all the areas of each side will give you total surface area
Your equation should look like:
2(4*2.5)+2(4*15)+2(15*2.5)=S
2(10)+2(60)+2(37.5)=S
20+120+75=S
215=S
Total surface area is 215cm
