The problem in the image asks:

Question: Salimah needs ten 350 ml cups of water to fill up Container X. What is the volume of Container X? Express your answer in litres and millilitres.

Solution:

1. Salimah uses 10 cups of water, each containing 350 ml.

2. The total volume of water required to fill Container X is calculated as: $\text{Total Volume} = 10 \times 350 \, \text{ml} = 3500 \, \text{ml}$

3. Since 1 litre (L) = 1000 millilitres (ml), convert millilitres to litres: $\text{Volume in litres} = \frac{3500 \, \text{ml}}{1000} = 3.5 \, \text{litres}$

Thus, the volume of Container X is 3.5 litres or 3500 millilitres.

Would you like further explanation or details? Here are 5 related questions to expand on this concept:

1. If one cup contained 500 ml instead of 350 ml, how much water would be needed for 10 cups?
2. How would the total volume change if you only used 7 cups instead of 10?
3. Can you convert 3.5 litres to gallons? (Hint: 1 gallon ≈ 3.78541 litres)
4. If Container X was only half-filled, what would its volume be in litres and millilitres?
5. How many cups of 250 ml would be needed to fill up Container X?

Tip: When converting between units, always make sure to remember the basic conversion factors like 1 litre = 1000 millilitres.
