A brick measures 25cm by 12 cm by 13 cm. What is the volume of the brick in cm3? How many milliliters of water would this brick displace?

Unfortunately, I can only answer the first part of the question. You want to find the volume. To do this, you need to multiply length * width * height. So 25 * 12 * 13. This gives you 3,900. 3,900cm cubes is your volume.
