It is pi*r2*h = 149628 cubic inches, approx

84951 cubic centimeters

Density = 0.05 kg/42000 cubic metres = 1.19*10-6 kg/m3

There can be no conversion.
A kilogram is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider a litre of air. How many kilograms? Next consider a litre of water. How many kilograms? The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.

419,328 cubic inches is 6.871 cubic meters.

Three lengths multiplied yield a volume not an area.

No, metric conversions will always be multiplying or dividing by a multiple of ten. Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). These are the denominations you need to list when converting metric units. Liters are three places to the left of milliliters. So you have to move the decimal place three times to the left (same as dividing by 1000). You will get 7000 mL = 7 L.

If it is a rectangular tank, the volume is length times width times height, 6m x 6m x 3m, or 108m3.

There are 0.028 litres in an ounce.

There are 16 ounces in a pound, so multiply the number of pounds by 16 to get ounces.

One cubic yard is equal to 363 = 46656 cubic inches. Therefore, 625 cubic yards is equal to 625 x 46656 = 29160000 cubic inches.

There are 5,000 milliliters in 5 liters.

No. They're the same volume.

one
One cc is equal to one ml and these measurements can be interchangeable.

You can't convert that.

Cubic feet is a unit of volume.

Acre is a unit of area.

They are cuberoot(3) = 1.442 metres (approx)

1.4 liters is 1,400 mL (1 liter = 1,000 mL).

12 cubic meters = 423.78 cubic feet.

1 liter = 2.11 pints

1 pint = 0.47 liter
