Question

Marisha wants to measure the volume of a rock. She pours water into a graduated cylinder and it measures 200 mL. Then she drops the rock in it, and measures the water level at 297.5 mL. The volume of the rock is the difference between the water level before and after. What is the volume of the rock

Answer 1

Answer:Volume of Rock= 97.5ml

Explanation:

STEP 1

Finding the volume of rock using the graduated cylinder that measures volume of liquid can be done by determining how much water is being displaced by the rock after submersion.

Step 2

Volume of water before adding rock = 200mL

Volume of water after adding the rock = 297.5mL

Volume of rock =Volume of water after adding the rock - Volume of water before adding rock

Volume of Rock = 297.5-ml 200ml

= 97.5ml
