Question

John wants to know the volume of his gold ring in cubic centimeters. He gets a glass in the shape of a rectangular prism with a base 3\text{ cm}3 cm3, space, c, m by 2\text{ cm}2 cm2, space, c, m and fills the glass with 3.1\text{ cm}3.1 cm3, point, 1, space, c, m of water. John drops his gold ring in the glass and measures the new height of the water to be 3.7\text{ cm}3.7 cm3, point, 7, space, c, m. What is the volume of John's ring in cubic centimeters?

Answer 1

Answer:

the answer above is right

Step-by-step explanation:

Answer 2

For this case the first thing to do is find the volume of the rectangular prism without the ring.
 We have then:
 $v1 = (3) * (2) * (3.1) v1 = 18.6 cm ^ 3$
 We now look for the volume of the rectangular prism with the ring:
 $v1 = (3) * (2) * (3.7) v2 = 22.2 cm ^ 3$
 Then, the volume of the ring will be the difference in volumes.
 We have then:
 $v = v2 - v1 v = 22.2 - 18.6 v = 3.6 cm ^ 3$
 Answer:
 The volume of John's ring in cubic centimeters is:
 $v = 3.6 cm ^ 3$
