Lake superior is the largest of the great lakes, with a volume of 2900 mi3. how many gallons of water are contained in lake supe

amid [387]

we are given

Volume of water in lake in mi^3

$V=2900mi^3$

now, we know that

$1 mi^3= 1.10111715*10^{12} gallons$

we can multiply both sides by 2900

$2900*1 mi^3= 2900*1.10111715*10^{12} gallons$

$2900*1 mi^3= 3193.239735*10^{12} gallons$

we can write in scientific form

$2900 mi^3= 3.193239735*10^{15} gallons$ ...........Answer
