Question

When water freezes its volume increases by 9 percent. how many cubic meters of water must freeze in order to oproduce 545 cubic meters of ice?

Answer 1

let
x------> cubic meters of water
y-----> cubic meters of ice

we know that

y=1.09*x------> x=y/1.09
y=545 m³
x=545/1.09
x=500 m³

the answer is
500 m³ of water
