Question

Jamie wants to know the volume of his gold ring in cubic centimeters. He gets a rectangular glass with a base 3 cm 3 cm by 2 cm 2 cm and fills the glass 4 cm 4 cm high with water. Jamie drops his gold ring in the glass and measures the new height of the water to be 4 . 2 5 cm 4.25 cm. What is the volume of Jamie's ring in cubic centimeters?

Answer 1

Volume of water in the glass = 3 x 2 x 4 = 24 cubic cm.

Volume of water plus the ring = 3 x 2 x 4.25 = 25.5 cubic cm.

Subtract the total with the ring from just the water:

25.5 - 24 = 1.5 cubic cm
