A microwave runs off a 110. V circuit and draws 7.00 A of current. How much water would

be required to run the microwave for 10.0 minutes if it is powered by a 10.0­m high water
wheel?

I really don't this question nor know what exactly i'm suppose to be finding, please help

How many Joules are needed?

power = Vi = 110*7 = 770 watts
energy = power*time = 770*600seconds 462,000 JOULES needed

= m g h
= m (9.81)(10)

so
m = 4709 Kilograms of water
there are 1000 kg of water/meter^2
so
4.709 cubic meters of water
