Find the volume v and surface area s of a closed rectangular box with the following length, width, and height.
00:10
Well, it says the length is 8 feet.
00:16
So we're going to put 8 right here.
00:18
And it says the width is 4 feet.
00:22
So we'll put 4 right here.
00:25
And then it says the height is 7 feet.
00:31
Okay, so i have the formulas for volume and surface area written down here.
00:36
We're going to start with volume.
00:41
Volume equals length times width times height.
00:46
So we'll start with our eight, our length, times our width, which is four, times our height, which is seven.
01:10
Our total volume, when we multiply them all out, is 224.
01:17
Since we're talking about volume, we want to put our units, which in this case is feet, and cubed units because we're dealing with three dimensions.
01:33
So the volume would be 224 feet cubed...
