Volume

Volume = pi*r2*h = pi*6.82*(2*12) cubic inches = 3486 cubic inches, approx. = 2.02 cubic ft.

Use a variant of Archimedes Principle. Immerse the person completely in a tank of water (only do this for a short period of time, of course) and measure the rise in the water level and multiply by the area of the tank to get the change in volume.

8"=.666 of 1' so .666'x70'x4'/27=6.912cu. yrd.

1 liter = 1000 cc = 1000mL so multiply 250 by 1000 for the answer of 250,000 cc.

1 US gallon ≈ 3.785 liters

3,450 US gallons ≈ 3,450 × 3.785 liters ≈ 13,060 liters.

1 Imperial gallon ≈ 4.546 litres

→ 3,450 imperial gallons ≈ 3,450 × 4.546 litres ≈ 15,684 litres

Remember K H D | d c m. Litres is three places to the left of millilitres. So you have to move the decimal place three times to the left. So in this case the answer is 0.234 litres.
234 mL is 0.234 liters (1 liter = 1,000 mL).

This is not really a valid conversion because cubic meters is a measure of volume while meters is a measure of length or distance.

You cannot convert square yards to cubic yards. One is a measure of area and the other is a measure of volume.

If you have a cube with edges 3 yards long the area of each face will be 3 x 3 = 9 square yards. The volume of the cube will be 3 x 3 x 3 = 27 cubic yards. Was it perhaps something along these lines that you meant?

The volume is 3,817 units3

There's a large number of possibilities for that. It depends on what the height (depth) is.

If it's 1, then there are 4 possibilities using only integers:

1-40

2-20

4-10

5-8

If it's 2 then possibilities are:

1-20

2-10

4-5

If it's 4 then:

1-10

2-5

If it's 5 then:

1-8

2-4

If it's 8 then:

1-5

If it's 10 then:

1-4

2-2

If it's 20 then:

1-2

If it's 40 then:

1-1

So, using only integers there are 16 possibilities.

Volume = pi*12*7 = 7*pi cubic feet

You do not.

A nanometre (nm) is a measure of length or distance in 1-dimensional space while a cubic centimetre is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.

The question cannot be answered without information about the units of measurement.

The relationships between cubic inches and cubic feet, or cubic centimetres and cubic metres are not the same.

1.6 liters are about 1.69 US quarts.

1 liter ~ 1.05669 US quarts
1 US quart ~ 0.946353 liters

That is approximately 6.4 tablespoons.

4, 3, AND 2

There can be no conversion. A cubic metre is a measure of volume in 3-dimensional space, whereas square feet is a measure of area in 2-dimensional space. The two measure different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
