So here we have a side view of a swimming pool.
00:03
So it's 20 feet long and six feet deep on one end and three feet deep on the other end.
00:08
We also know that it is 15 feet wide.
00:13
So we're going to think about this all going back 15 feet.
00:20
And i'm going to think about breaking this into two different pieces.
00:24
So one of them will be a rectangular prism.
00:27
And one of them will be a trapezoid prism.
00:30
So let's start with our rectangular.
00:32
Prism.
00:37
So that volume will be the length times the width times the height.
00:42
So we're just looking at this part here.
00:47
So that is a length of 10, a width of 15, and a height of 6.
00:54
So that volume will be, let's see, 15 times 6 is 90 times 10 is 900.
01:02
So we have 900 cubic feet here.
01:05
And now we're looking at the trapezoid, the old prison...
