Imagine the Olympic swimmer diving into the pool

and swimming the entire length.

From the point of view from the Olympic swimmer,

the surface area is:

15 x 1 + 8 x 1 + 8 x 1 + 15 + 8 + 8 = 31.

The other side is the same, so double that is

**62**. THere are two side walls:

THe surface area is 18 x 1 + 18 x 1 + 9 x 1 + 9 x 1 + 18 x 9 + 18 x 9

= 18 + 18 + 9 + 9 + 162 + 162 = 378.

The other wall is exactly the same, so double that is

**756**. Finally there is the bottom of the pool.

2 x 18 x 1 + 2 x 1 x 13 + 2 x 13 x 18 =

36 + 26 + 468 =

**530****Total 1348**
