Introduction to Volume Volume: • Number of cubic units in a 3D figure • V=lwh • Measured in cubic units or units 3
Find the volume.
V = lwh V=6 × 3x2 V = 18 × 2 V = 36 cu. cm or 36cc3
Find the volume.
V = 3,600 cu. in. V = 270 ff 3 V = 350 cu. yd.
Constructing Graphs from Gathered Data Use student work-text page 233 to gather data and create a bar graph. Topics might include favorite ice cream, pets, eye color, colors in M&M bag, etc.
Why do we use different types of graphs (pictograph, bar graph, line graph) instead of just one kind? When would you choose each type? Suggested Answer: We use different types of graphs because they highlight different types of information. Just like you use different tools to build a Lego set, like a brick separator for stuck pieces or a screwdriver for tiny axles, you use different graphs to tell the story of your data.
