If we suppose that the volume of lake reason is about 2.56x10^5 km^3 and lake reason is 20 times the volume of lake rushy. Write the volume of lake rushy
Note......20 = 2 x 101
So....we have
[2.56 x 105 ] / [ 2 x 101 ] =
[ 2.56 / 2 ] x [105 / 101 ] =
[ 1.28 ] x [ 104 ] =
12800 km^3 = volume of Lake Rushy
