Answer:
B) 
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:

The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:

Finally, we sum both of the areas found to calculate the total area.

So, the answer is option B).
Answer:
7 balls
Step-by-step explanation:
Look for the worst case scenario:
Get 3 white, 2 green, and 1 black.
That adds up to: 3 + 2 + 1 = 6.
+1 red ball: 6 + 1 =7
7 balls
Base or base number
for example 2^3 = 2 * 2 * 2 or x^2 = x * x
