Answer: The volume of object is

Step-by-step explanation:
We are given:
Volume of water in graduated cylinder (without object),
= 35.0 mL
Volume of water in graduated cylinder (with object),
= 38.5 mL
Volume of object =
= 38.5 - 35.0 = 3.5 mL
Converting this value in cubic centimeters, we use the conversion factor:

So,

Hence, the volume of object is
