A HEXAGONAL AQUARIUM. EACH OF THE SIX SIDES IS 16 INCHES BY 23 INCHES. HOW MANY GALLONS OF WATER WILL THIS FISH TANK HOLD?

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.

volume requires 3 measurements:

height, width and depth (from front to back)

Once you have the 3 dimensions you can multiply them together to get the volume in whatever unit you measure in, Centimeters/Inches/feet etc.

once you have your volume you can google a conversion table to figure out your unit to gallons/litres/ etc.

Add 38 gallons of water to the current mixture assuming you have a 250 gallon tank. This will bring your current ration back to 32 to 1

99 gallons / 23 = 4.3

4.3(32-23)=38.7

99 gallons + 38 gallons = 137 gallons.

250 gallons - 137 gallons = 113 gallons Left to fill

113/32 = 3.5

Add 3.5 gallons of coolant to the remaining 113 gallons of water needed to fill your tank completely.

99 gallons / 23 = 4.3

4.3(32-23)=38.7

99 gallons + 38 gallons = 137 gallons.

250 gallons - 137 gallons = 113 gallons Left to fill

113/32 = 3.5

Add 3.5 gallons of coolant to the remaining 113 gallons of water needed to fill your tank completely.

the volume of the tank is calculated by the formula

22/7 x 24 x 4

= 301.7143 cubic feet

1 cubic foot = 7.48052 US Gallons

therefore your tank will hold 2257 US gallons approximately

22/7 x 24 x 4

= 301.7143 cubic feet

1 cubic foot = 7.48052 US Gallons

therefore your tank will hold 2257 US gallons approximately

About 488 cubic feet or about 3650 US gallons.

72 x 29 x 24 = 50,112 cubic inches / 1728* = 29 cubic feet. There are 7.48 gallons per cubic foot, so the tank is actually 216.92 gallons, assuming the dimensions given are inside measurements. I hope you have a strong stand and floor because the water alone weighs 1735.36 pounds (8 pounds per gallon).

*12 x 12 x 12 = 1728 (cubic inches to cubic feet conversion)

*12 x 12 x 12 = 1728 (cubic inches to cubic feet conversion)

How many watts you
need depends on the type of plants and the volume of the tank. Here is an excerpt from an article that will
help you determine proper wattage.

Instructions

Identify
the species of plants you have in your tank or that you plan to put in your
tank and how much light that species needs. Each species of plant will have an
optimal lighting requirements, from low light to bright light. To determine the
plant species, compare photos on the Aquarium Plants Photos and Profiles page
of the Aqua Hobby website, or take samples of the aquatic plants to your local
aquarium store for identification.

Write
down how much lighting each of the plant species in your tank needs. Give each
plant a rating of low, medium or bright. The books "The Complete
Fishkeeper" and "Freshwater Aquariums for Dummies," as well as
your local fish store, are good sources of information for this.

Review your
list and determine what type of plant dominates your tank. For example, if you
have mostly plants that need bright light, then use a bright-light formula. If
you have an equal mix of plant lighting needs, then use a medium-light formula.

Calculate
a range of watts of lighting you need for your tank with one of the following
formulas, depending on the amount of light you determined you needed for your
plants. For low light, multiply one and two by the number of gallons. For
medium light, multiply two and three by the number of gallons. For bright
light, calculate three and five by the number of gallons. For example, for a
20-gallon tank with plants that need medium light, you would get a range of 40
to 60 watts (2 x 20 = 40 and 3 x 20 = 60).

The general rule of thumb is that all of the water inside your tank should pass through the filter at least four times per hour. This equation should make it easier for you to calculate. Here is an example - a 30 gallon tank needs a flow rate of 120 gallons per hour.

Aug 14, 2012 | Fish

A flow rate is the amount of gallons your water pump can push in an hour. Water pump should be able to push five times as many gallons as the of the tank. For example if you have a 20 gallons tank you'll need to use a water pump with a minimum of 100 gallons flow rate.

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
