We can see this rectangular prism will have side lengths of 5, 3, 7.
So we can use the fact Surface Area = 2(lh+wh+lw) to get:
2(15 + 35 + 21) = 2(71) = 142
Answer:

Answer:

Step-by-step explanation:
Lets use the compound interest formula provided to solve this:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
First, change 6% into a decimal:
6% ->
-> 0.06
Since the interest is compounded semi-annually, we will use 2 for n. Lets plug in the values now and your equation will be:

Answer:
120 ways
Step-by-step explanation:
Since no girl wil sit either first or last
