Answer:
5 cm³.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of Rock =.?
The volume of the rock can be obtained as follow:
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 40 – 35
Volume of Rock = 5 mL.
Finally, we shall convert 5 mL to cm³.
This can be obtained as follow:
1 mL = 1 cm³
Therefore,
5 mL = 5 mL × 1 cm³ / 1 mL
5 mL = 5 cm³
Thus, we can say that the volume of the rock is 5 cm³.
