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.

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.
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.
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.
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.
