Final answer:
To make the jug 4.5 liters, you will need 10 ice cubes.
Step-by-step explanation:
To find out how many ice cubes are needed to make the jug 4.5 liters, we need to subtract the current volume of the jug (3 liters) from the desired volume (4.5 liters). This will give us the additional volume needed.
Additional volume needed = Desired volume - Current volume = 4.5 L - 3 L = 1.5 L
Now, we can calculate the number of ice cubes needed. Since each ice cube is 150 ml (0.15 L), we can divide the additional volume needed by the volume of each ice cube:
Number of ice cubes needed = Additional volume needed / Volume of each ice cube = 1.5 L / 0.15 L = 10 ice cubes
