In problem five, we are shown a diagram of a birdhouse that elena is planning to build.
00:07
And we're asked to determine about how many square inches of wood will she need to build this birdhouse.
00:13
So we're basically asked what is the surface area of this birdhouse.
00:17
So what i'm going to do here is find the area of each of these sides, and then go ahead and add them together at the end.
00:26
So here we have 5 .5 times 9 .25 for the front.
00:42
We multiply those together.
00:46
Get 50 .875 inches squared.
00:53
Then over here, i'm going to go ahead and find the surface area of this portion.
01:01
To do that, i'm going to have to cut this off right here.
01:08
So i'm going to do 9 .25 times 5 .5 again.
01:12
So that's actually going to be the same for all three of these sides.
01:17
So i'm going to go ahead and multiply that by three, which gives me 152 .6255 inches cubed.
01:32
So that's for front and sides...
