Answer:

Step-by-step explanation:
In order to solve this you just have to remember the formula for the sides and hypotenuse of the triangle rectangle:

Since A and B are equal we will use X to represent them both:

ANd by solving the equation we get that the length of the legs of the triangle rectangle with a hypotenuse of 4cm is 
i = 3c
i = c + 14
set both equations equal to each-other, we can
solve for c, we must.
3c = c + 14
subtract c from both sides, we must.
2c = 14
divide both sides by 2, we must.
c = 7

if you multiply 10.4x5x8 it equals 416 millimeters
Answer:
416 mi
Step-by-step explanation:
In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.
<em>Remember to find the area it is length x width</em>
- 9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
- Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
- In total, you will add 72+72+72+72+64+64 which equals 416
