How do you find the volume for an irregular object?

• A. Measuring with a ruler
• B. Water Displacement
• C. Using a graduated cylinder
• D. Estimating by appearance

Answer: (B)

Finding the volume of an irregular object is done through water displacement. Irregular shapes don’t have a simple length × width × height, so you determine their volume by the amount of water they push aside. Fill a graduated cylinder with a known amount of water and record the starting volume. Submerge the object completely, making sure no air pockets cling to it, and measure the new water level. The difference between the final and initial readings is the object's volume. Use milliliters, since 1 mL equals 1 cubic centimeter, so the number you read is the volume. This method works because the submerged object occupies space that water must move into. Measuring with a ruler or guessing by appearance won’t give an accurate volume for irregular shapes, and trying to measure dimensions directly isn’t effective for such objects.
