Lake Superior contains 3.0 x 10^15 gallons of water. How many cubic meters of water are contained in the lake? Express your final answer in scientific notation.

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.



answer:

2

explanation:

1+1 = 2

the reason this is so is because of basic addition. we can double check this without using addition if you really want. if you take 1+1=x, subtract 1 from both sides than you get 1 = x - 1. subtract x from both sides and you get 1 - x = -1. subtract 1 from both sides again and you get -x = -2. finally, multiply both sides by -1 to get x = 2. subtraction is still technically addition you say? fine, have it your way. 1 + 1 = x. by definition, adding something to itself is the same thing as multiplying it by 2. this means we can technically rewrite the equation as

1 * 2 = x. now all we have to do is solve it. 1 * 2 = x when simplified results in 2 = x, or x = 2. this shows 1 + 1 = x. you say you want a real answer. you want me to start you from the ground up? well i would, but that would practically just be stealing from what was written on this website: go check it out if you really need to.
