In general, what's the volume of a prism? a prism has a base that's parallel to both sides.
00:06
So my base here is probably a rectangle.
00:09
So this is a rectangular prism.
00:12
The volume is always area of the base, not just the base, but area of the base times the height.
00:19
And the height is the distance between the two bases.
00:21
So my base is, my height is going to be approximately 1 .5 feet will be my height.
00:28
And my base is a rectangle with dimensions three and a half feet times two and a half feet.
00:35
So before i multiply these terms, let's just convert them to improper fractions.
00:42
So the way to do this, one and a half feet, i'm going to multiply then add two times one is two plus one is three over two.
00:51
This is equivalent to three over two.
00:52
Three and a half, three times two plus one is the same thing as seven over two.
00:56
And then 2 .5, 2 times 2 is 4 plus 1 is 5 over 2...
