3.9L
Explanation:
Initial volume = 25L
Final volume = 28.9L
The initial volume is the volume of the liquid without the metal in originally in the container. It is 25L
After adding the metal, the volume changes to 28.9L
Final volume = Initial volume + volume of metal
To find the volume of metal make it the subject of the expression;
Volume of metal = Final volume - initial volume = 28.9 - 25 = 3.9L

Sometimes the volume of water displaced is the volume of the solid.
