Finding Volume!!

What is Volume? Volume- A measure of the size of something in three-dimensional space Volume Measures: Solid Liquid Gas

Volume of a Solid Measured in meters Given in cubic units, such as cubic meters, cubic centimeters, or cubic millimeters. Formula of a box-shaped object: Length X Width X Height

Activity On a half sheet of Paper: With a partner, find 2 box-shaped solids in the room to measure with a ruler. Write down what the object is Write down the units of the length, width, and height of the object Calculate and write down the volume of each item

Volume of a Liquid Measured in Liters Given in units such as Liter (L) or milliliter (mL) Measured using graduated cylinder **Fun Fact: Lake Erie, the smallest of the Great Lakes, has a volume of approximately 483 trillion liters of water (483,000,000,000,000L)

What is a Meniscus? A Meniscus is the curve at a liquid’s surface by which one measures the volume of a liquid. To measure volume accurately, you must measure from the bottom of the meniscus!

Volume of Irregularly Shaped Objects Determined by the volume of liquid that the object displaces or “moves out of the way” Things that have volume cannot share the same space

- Volume of water started at 4.8 mL - After toy was put in, volume of water was at 5.6 mL - Therefore, you would do: 5.6mL – 4.8mL = .8 mL So, the volume of the toy is .8 mL

Because the toy dinosaur is a solid, we must express his units in cm3, not in mL 1 mL = 1 cm3 Therefore, the volume of the toy dinosaur is .8 cm3 (.8 mL = .8 cm3)
