What is the volume of Jamie's ring in cubic centimeters?

Answer 1

1.5

Explanation:

Answer 2

1.50 cm^3.

Explanation:

The ring will displace its own volume of water.

The increase in height of the water = 4.25 - 4 = 0.25 cm.

Therefore the increase in the volume = area of the base of the glass * 0.25

= 3 * 2 * 0.25

= 6 * 0.25

= 1.50 cm^3.

This is also the volume of the ring.
