Finding the Density of Objects Volume • The _________________ of ___________ occupied by an object is called its volume. • If you want to know the volume of a solid rectangle, such as a brick, you measure its _____________, _____________, and, ______________ and multiply the three numbers and their units together (V = 1 x w x h). Measuring Volume • For a brick, your measurements probably would be in ___________________. • The volume would then be expressed in ________________, cm3. • In measuring a liquid’s volume, you are indicating the ________ of the container that holds that amount of liquid. • The most common units for expressing liquid volumes are __________ and ________________. • A liter occupies the same volume as a _____________ ________________, dm3. • A cubic decimeter is a cube that is 1 dm, or 10cm, on each side. Measuring Matter • Mass is a measurement of the __________________ of matter in an object. • Density of a material does not change even if the shape of the object does because it is still the same material. It still has the same “stuff” in it. Density • The ____________ and _____________ of an object can be used to find the density of the material the object is made of. • _____________ is the mass per unit volume of a material. • You find density by _________________ an object’s mass by the object’s volume. • Combination of base units. • Mass-Base unit: kilograms (kg) Grams (g) and milligrams (mg) are used for measuring objects of small mass. • Volume - length width height 1 cm3 = 1 mL • Density - mass per unit volume (g/cm3) Copy Triangle GIVEN: V = 825 cm3 D = 13.6 g/cm3 M= GIVEN: M = 620 g V = 753 cm3 D=? 1 dm3 = 1 L
