Okay, so this question basically asks us to actually calculate the mass of the goal that we need.
00:12
So the mass is equal to the density times the volume.
00:19
Here the density is given, and then what we need to do is calculate the volume, the v.
00:29
Now we can try to calculate the volume.
00:31
So for the shit, we actually need the volume of the shit is actually equals to the surface of the sheet and times the thickness of the shit.
00:55
So first, the surface is already given, which is 100 feet times 82 feet.
01:05
But we need to convert that to the centimeter square.
01:12
So we know 1 fit equals to 30 .48 centimeter.
01:24
So now we can actually convert that into.
01:30
So 100 feet times 82 feet equals to 100 times 30 .480.
01:38
8 cm times 82 times 30 .4a centimeter.
01:50
And here you can just use a calculator to do the calculations, and which actually equals to around 7 .618 times 10 to 6 .6 centimeters square.
02:19
And how about the thickness? the thickness, h, is also given, which is 5 mili months of an inch.
02:35
So 1 milamance is actually equals to 0 .054 milliliter.
02:46
So it says it's 5, so the thickness just simply equals to 5 times 0 .0 .0 .4 millimeter.
02:57
024 millimeter.
03:01
And we have to convert that into the centimeter, right? so it's actually equals to 0 .01 to 7 centimeter...
