If the ship is so dense, why does it float? Huh?

Another idiot weighing in----Your quote: "They (obviously you mean
right) are much less dense than the water they
You know just enough to be dangerous (and stupid).
The density of water is 62.4 lbs/cubic ft
The density of steel is approx 490 lbs/ cubic ft---- Got it???? Steel
specific gravity of approx 7.8--you do know what SG is, don't you?
Apparently you don't know enough about the current topic to jump
keep your mouth shut so you don't look so foolish.
Because you need some help--"Archimedes"--Ever hear of him????
35 gal is correct. 1 cu ft = 7.48 gallons
28x18x16 = 8064 cu in
8064 div by 1728 cu in per cu ft = 4.6 cu ft
4.6 cu ft x 7.48 gal/cu ft = 34.4 gal
13x12x18 = 2808
2808/1728 = 1.625
1.625 x 7.48 = 12.155 gal
Both are correct...
~12.2 gallons & ~34.9 gallons
For reference the key for an easy calc is ...... 231 cubic inches per
12" x 13" x 18" = 2808 cbiuc inches
2808 cubic inches / 231 cubic inches per gallon = 12.2 gallons
You can do math using the google search field; in your case, it would be
"x cubic inches to gallons", where "x" is the product of 28x18x6.
To put this all into one line, you could use the following syntax:
(28 * 18 * 6 ) cubic inches to gallons
First, the approximation:
The larger tank is about twice as long, and 1.5 times as wide, as the smaller
one, while their
heights are about the same -- so one would expect that its capacity is about 2 x
1.5 = 3 times
that of the smaller tank. If the smaller one is around 12 gallons, you should
expect the larger
one to be around 36, which matches well with the claimed size of 35.
Now the exact calculation:
28 x 18 x 16 = 8064 cubic inches. There are 12 x 12 x 12 = 1728 cubic inches in
a cubic foot,
so 8064 cubic inches is 8064 / 1728 = 4.67 cubic feet.
One cubic foot is about 7.5 gallons, so 4.67 cubic feet = 35 gallons.
Your smaller tank is 13 x 12 x 18 = 2808 cubic inches = 1.625 cubic feet = 12.2
