Answer:
1,534 inches squared
Step-by-step explanation:
To find surface area we just solve for the area of all the sides and add those together. A rectangular prism (a box like above) has 6 sides. There are...
2 sides each of the following dimensions:
2(13×26)=
2(338)=676
2(13×11)=
2(143)=286
2(26×11)=
2(286)=572
Add the area of all 6 sides...
676+286+572=1,534
Remember it is squared not cubed.

3(x-2)-6
3x-6-6
3x-12< your answer </span>
Let the original price of the book be x. If, after a 33% markup on the initial price, the student had to pay 115.00 for it, then we can calculate x as:
(1 + 33%)(x) = 115
1.33x = 115
x = 115/1.33 = 86.47
This means that the bookstore paid $86.47 for the book.
Answer:
perimeter = sum of all sides. this is same for polygons
rect: area l×b. peri = 2(l+b)
Step-by-step explanation:
15+5 = 20
20*2 = 40 cm is the perimeter of the given figure
