So we have to figure out the volume and density of this rectangular block.
00:06
And this is a pretty straightforward problem.
00:09
So they give you the length, the width, and the height, in centimeters of this block, and we need to figure the volume and the density.
00:17
So we're going to need the volume.
00:19
I have the equations on the left side of this whiteboard.
00:21
We're going to need the volume to solve for the density, and we're given the mass.
00:25
So let's start by solving for the volume.
00:28
So the volume is going to be 2 .9 centimeters.
00:34
I don't know why that happens.
00:38
2 .9 centimeters times 3 .5 centimeters times 10 .0 centimeters.
00:48
And when you do that and round to two significant figures, you should get 100, but you could express that 100 as 1 .0.
01:02
0 times 10 to the second.
01:07
So two significant figures because 2 .9 and 3 .5...
