Answer:
Step-by-step explanation:
v = 45 * 12
v = 540cm³
To fill the tank,
v = 45 * 25
v = 1,125cm³
I'm not quite sure what the exact question is so i'll answer both;
1.) The volume of water required to fill the tank from empty = 1,125cm³
2.) The volume of water required to fill the tank from it's current level is
1,125cm³ - 540cm³ = 585cm³
