Question

A rook is dropped into a graduated cylinder filled with 35 mL of water.

What is the volume of the rock? (Hint: 1 ml water = 1 cm?)
40 cm
O 14 cm
O 5 cm
O 35 cm

Answer 1

5 cm³.

Step-by-step explanation:

The following data were obtained from the question:

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 illustrated below:

1 mL = 1 cm³

Therefore,

5 mL = 5 cm³

Thus, the volume of the rock is 5 cm³.
