You are watching: How do you find the volume of a irregular shaped object

To find the volume of a rectangular object, measure up the length, width and also height. Multiply the size times the width and multiply the result by the height. The result is the volume. Provide the result in cubic units, such together cubic centimeters. Calculation a cube together you would any other rectangle-shaped object.

To uncover the volume of a cylinder, measure the diameter across the round finish at the widest point. Measure the height. Approximate pi together 3.14. Multiply 3.14 time the diameter. Main point the an outcome by the diameter again. Main point this result by the height. Division the total by four. The result is the volume the the cylinder.

Find the volume the a sphere. Lay the round down on document or top top the ground. Keep in mind where the widest suggest is across the sphere. Take far the sphere and measure this line, which is the diameter. Main point 3.14 times the diameter time the diameter time the diameter. In other words, multiply the diameter cubed through 3.14. Divide the full by six. The an outcome is the volume that the sphere.

To find the volume of a cone, sit the cone down on its flat bottom next to a wall. Top top the wall, measure from the bottom that the cone to the height of the cone to gain the height. Measure up the diameter that the bottom that the cone in ~ its widest part. Multiply 3.14 times the diameter times the diameter time the height. Division the complete by 12. The result is the volume that the cone.

Use the water displacement an approach to measure irregular objects such together a ring, a rock or a spoon. On the teachers Network, Natasha Cooke explains that this procedure is a an easy use of measurement and also subtraction. Fill the manufacturer with enough water that allows the irregularly shaped object to fit inside it. Keep in mind the level of the water in ~ this suggest and write the water level without the object.

Place the object down right into the water. Look in ~ the level that the water again and an alert that it has risen. Note down the new number of devices that you measured in the beaker. This is the level consisting of the object.

Subtract the level without the object from the level consisting of the thing to reach the volume that the irregularly shaped object. The result may it is in in millimeters if you used a traditional beaker.
