Answer:

1,100

Step-by-step explanation:

15*10*2=300

20*15*2=600

20*10=200

300+600+200=1,100

you need to find the surface area which means the area of all the sides except the top(bc i think its open???)

a shortcut i used was multiplying sides that have the same area by 2. for example, the side 15*10, there was another side like that, so i multiplied by two instead of having to solve for the other side individually, does that make sense?

check my math if im wrong
