00:01
So we know that for part a, the density is equaling the mass over the volume.
00:05
And for the volume, we could say that this would be, again, the mass divided by the volume.
00:11
But the volume here would be the length times the base times the height.
00:19
And so we're solving for the height.
00:21
This would be equal to the mass divided by the length times the base times the density.
00:26
And so the height would be equaling 50 ,000 grams divided by the length 90 centimeters, multiplied by the base of 50 centimeters, multiplied by the density of 0 .68 grams per cubic centimeter.
00:50
And we find that the height is 16 .3 centimeters, or we can say 0 .163 meters.
01:01
And so this would be the depth of tank.
01:10
And then for part b, they're asking us, for part b, it's asking us discuss whether this tank has a reasonable volume for a passenger car...
