Hey there!
The answer is .
We can find the surface area by finding the areas of each rectangle, and adding them up!
The four long rectangles each have a length of 6, and a width of 8, so their area is 6 x 8, or 48. There are four rectangles, so 48 x 4 = 192.
Next, we have two squares, each with a length of 2 and a width of 6, therefore their area is 2 x 6, or 12. There are two squares, so 12 x 2 = 24.
Now, we add the numbers: 24 + 192 = 216.
Have a super awesome day! :)

Using a geometric sequence, it is found that after 3 rounds, 8 teams are left.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
In which is the first term.
In this problem:
- 64 teams were invited, thus
.
- After each round, half the teams are eliminated, thus
.
The <u>number of teams after 3 rounds</u> is the 4th term of sequence, as the first is the initial number(0 rounds), thus:
After 3 rounds, 8 teams are left.
