So this assignment has to do with using the formula for the volume of a rectangular prism.
00:06
The volume of a rectangular prism is the length times the width times the height.
00:10
And they give us several questions where they actually give us a picture and ask us to find the volume.
00:15
So the first question asks us to find the volume of a rectangular prism that has a length of five centimeters, a width of three centimeters, and a height of four centimeters.
00:27
So five by three by four.
00:30
And when i multiply those together, i get 60 centimeters cubed.
00:37
The second question gives us a prism with a length of three, a width of two, and a height of nine.
00:43
So three times two times nine.
00:45
And when i multiply those together, i get 54 cubic centimeters.
00:52
The third question gives us a prism, but in the picture, i think it's cut off a little bit.
00:57
They tell us that the width or the length is six meters and the height is seven meters, but they don't give us a width.
01:03
So again, using the same idea, if i did six by seven, and then let's just use w for width, that would be 42 w meters cubed.
01:14
And i don't think this was intentional.
01:15
I think it was an accident that it was cut off.
01:17
So let's say that just to give an example of what we would do, let's say that our width is five.
01:23
So it would be six times seven times five.
01:26
So 42 times five is 10, 20, 130.
01:31
Nope, i think i did that wrong.
01:36
So two times five is zero carry the one, 20 plus one, 210.
01:43
42 times five...
