Question about Calculators

If it was 1/2 full, and is now 1/8 full, that means 3/8ths was removed. So 3/8ths of a tank = 420 gallons.

Divide by 3, and you get 1/8th = 140 gallons.

Multiply by 8, and you get 1120 gallons total capacity of the tank.

Wow! I just happened to be browsing for a different purpose, and I read this question, then looked at the answer.

The way you wrote the answer out somehow opened a memory

"block" of mine and I was able to fully understand it! When I couldn't have done it before! I'm talking a matter of years. I'm now 51 years old and I couldn't have done this TWENTY years ago. Or, maybe I had it all along and somehow you just smacked me on the right side of the head to knock out my cobwebs. (Right, as in correct, not as in opposite of left, lol).

This may not sound like much to some of you, but for me, struggling with memory problems and physicall illness, etc. this was a pretty major breakthrough for me. I just wanted to thank you!

About 488 cubic feet or about 3650 US gallons.

I assume the length of a side is 16 in, and the height of the prism is 23 inches.

**Volume of a prism is V_prism=(Area of base)*(height of prism)**

Area of base is made up of the area of the 6 equilateral triangles with sides =16 inches. The height of such triangles is given by**8*SQRT(3)**.

Use the Pythagorean theorem or the trigonometric ratios to find the height of each of the 6 traingles.

Area of base =6*16*(8*SQRT(3))/2 sq in

**Volume =6*8*8*23*SQRT(3) cubic inches**

Calculate the value in cubic inches and convert to gallons: I leave that task to you.

A round tank 48" wide would have a circumference about 151"

The amount of water such a tank holds would depend on the height of the tank.

The gram (g) is a measure of mass (or quantity of substance). The mL is a unit of capacity (volume). What links them together is a physical characteristics called volumic mass or specific density (gravity).

That property depends on the substance. Some solid sunstances (aluminum) are light , others are very heavy (lead, mercury).

The reference density is that of water, which is taken to be 1.

Because of this a lot of people confuse the mass and the capacity, that is why we see questions like the one you just asked.

**It has meaning only if you are talking about liquid water at a temperature of about 4 degrees Celsius. At that temperature 1 gram of liquid water ocupies a volume of 1 mL or 1 cm^3. Thus, 135 g of water occupies a volume of 135 cm^3, or 135 mL. **

Two or three remarks: The Gallon is a unit of capacity (volume for fluids). So it cannot be converted into centimeters. In cubic centimeters yes, but not centimeters.

In addition to that there are two volume capacity units called gallons: the US gallon, and the imperial gallon. 1US gallon=3.7854 liters and 1 Imp. gallon=4.5460 liters.

To do your conversion use the facts that 1L =1000 mL=1000 cm³.

1 gal = 3785.4 cm³ or 4546 cm³.

Hi Kelma,

First determine the area to be filled

4 x 2 x 2 = 16 cubic ft

You need to determine how many cubic feet a gallon displaces.

Find out how many gallons the tank will hold by dividing:

Area to be filled / Displacement per gallon = Total capicity of tank in gallons

Best regards

Mike

Hello,

There is no fraction button. Any division of two integers you do is represented as a decimal number. If you want your fraction to remain a fraction you enter it as follows

**7[ / ] 19 [ MATH][1:ToFrac] [=] displays 7/19**

If you want to convert a decimal number into a proper fraction press**[MATH][1:ToFrac] .**

Exemple 7/19 [ENTER] gives .36842105. If without doing anything else, you press [MATH][1:ToFrac] you recover 7/19.

There are limitations related to the number of decimal digits in the floating point number.

.3684 [MATH][1:ToFrac][=] gives 921/2500 but

.36842 [MATH][1:ToFrac][=] gives .36842 : it is not converted to fraction.

Hope it helps
