Answer 1

Given that:

Lake Superior contains 3.0 x 10^15 gallons of water

Firstly, let's know that of 1 gallon;

1 gallon = 0.00375 cubic meter

Then, 3.0 x 10 ^15 = 3.0x10^15 x 3.785 x 10 ^-3

= 3 x 3.785 x 10^15-3

= 11.355 x 10 ^12m^3

Therefore, 11.355x10^12 cubic meters of water are contained in the lake.
