I assume you mean 0.09 dollars per kwh?
6 * 100w = 600w (joules per second)
600w / 1000 = 0.6kw
0.6kw * 6h = 3.6 kwh
3.6 kwh * 0.09 = 0.324 dollars
So your awnser is 32 cents

Other than light what two other forms of energy are in light bulbs?
I'm assuming that the light bulbs you're referring to are the normal light bulbs... Heat energy and electrical energy... that like cookies What do you mean by that like cookies alot??????????? Cookies are good...yum yum..
Why do ordinary light bulbs take more electrical energy than efficient bulbs?
The filament on normal light bulbs require a higher current of electricity to light up, and are more resistant to electricity as well. This causes it to use more electricity and generate more heat.
What are light bulbs that save energy called?
EcoSmart, ArmorLite, Philips, GE, and Sylvania all make a line of energy saving light bulbs. They all manufacture LEDs, CFLs, and halogen bulbs. All of these bulbs are comparable in performance and all of these products are energy savers.
What is the name of those swirly light bulbs?
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Does a light dimmer work with the new energy efficient light bulbs?
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
What are examples of electrical loads in the kitchen that convert electrical energy to light energy?
light bulbs switches
How is electrical energy transformed to light energy?
in bulbs.. in ovens.
What energy transformations take place when electrical energy is applied to light bulbs?
Electrical energy gets converted to light and heat energy.
Which energy changes light energy into electrical energy?
Different light bulbs, lamps, flashlights, LEDs.
Can electrical energy be converted into light and heat energy?
Yes. Consider lightning, or light bulbs.
What energy change occurs when one of light bulbs is turn on?
electrical energy
What does the light bulb do in a circuit?
Bulbs convert an electrical energy to produce light
Other than light what two other forms of energy are in light bulbs?

Which devise changes electrical energy into light energy?
Different light bulbs, lamps, flashlights, LEDs.
What energy is wasted in light bulbs?
Some of the electrical energy is given off as heat not visible light.
Can mechanical energy power light bulbs?
Not without being converted into electrical energy.
How is the new light bulbs energy renewed?
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.
