4. anonymous

what do you mean?

5. anonymous

find the total surface area of the box, then multiply that by $$0.7$$

6. anonymous

how do i find the surface of the area

7. anonymous

the area of a rectangle is base times height you know all the numbers you need for example, the rectangle in the front has base 11 and height 7, so the area is $$7\times 11=77$$

8. anonymous

there is another rectangle (in the back) with the same base and height so has area $$77$$ as well two more to go

9. anonymous

you got those?

10. anonymous

yep so i do 77 x 0.7 and ill get the answer?

11. anonymous

total surface area=2(l*b+b*h+l*h)
