Find the surface area of the rectangular prism

Step-by-step explanation:

The formula of a surface area of a rectangular prism l × w × h:

We have l = 5.5, w = 5 and h = 13. Substitute:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
