So, in this question, we have a specific weight that is weight divided by volume, which is equal to 520 lb divided by feet cube.
00:18
Now we have to find the density, which should be in si unit, that is meter cube per, sorry, meter cube kg divided by meter cube.
00:31
Now, we know that 1 lb is equal to how much? that is 4 .448 newton, okay? and 1 feet equal to 0 .3048 meter.
00:48
So if we do that, means if we put the value, means if we convert this into this form, then it will be automatically converted into si unit form.
00:57
So, 520 that is lb divided by feet cube multiplied by, it will be that is 4 .48 newton divided by pound.
01:17
So in this question, we have that is specific weight, that is 520 lb divided by feet cube.
01:30
Now we have to find the density, which should be in si unit, that is kg divided by meter cube.
01:36
So, what we have to do, we have to first convert this into si unit and after that we can find our density.
01:44
So to do that, we know that specific weight is what? specific weight is what? that is weight divided by volume, which is equal to 520 multiplied by.
01:54
Now, si unit of weight is newton and si unit of weight, sorry, volume is meter cube, okay? so we know that 1 lb is equal to, which is 4 .448 newton and 1 feet equal to it is 0 .3048 meter...
