Answer:
216 cm^2.
Step-by-step explanation:
There are 6 faces on the prism . 3 pairs with the same area.
The surface area = 2*6*10 + 2 * 6*3 + 2*3*10
= 120 + 36 + 60
= 216 cm^2.
Answer: OPTION B
Step-by-step explanation:
To solve this problem you must add the areas of each rectangle that form the prism;
The area of a rectangle can be calculated with the formula:

There are three pairs of equal rectangles, then you can find the surface area of 3 rectangles and multiply each one by 2, then you obtain that the surface area of the prism is:

Answer
V=19
You put a +11 under the -11 then you can move the +11 to the other side of the equal sign. Then u add them which equals 19.
They aren't similar because they're not proportional (the sides do not form equal ratios)<span />
