Let’s try some volume EXAMPLES. Ex 1)
Find the volume of the rectangular prism above.
Reasoning Mind Academy: Volume
Let’s try some volume EXAMPLES. Ex 1)
Step 1: Draw a picture! (One is already drawn for you, but always use a picture.)
Step 2: Label your dimensions on the figure’s picture. (What units does the problem give you? They are already labeled for you! )
Reasoning Mind Academy: Volume
Step 3: Write your SFS = Shape, Formula, Substitute for the problem using the given dimensions.
Shape: Rectangular Prism
Formula: V= l x w x h
Substitute= V= 4 (cubic units) x 2 (cubic units) x 2 (cubic units)
Reasoning Mind Academy: Volume
Step 4: Multiply your dimensions.
V = (4 cubes) x (2 cubes) x (2 cubes) V = (8 cubes) x (2 cubes) V = 16
Reasoning Mind Academy: Volume
Step 5: Box your answer and write the correct units for your answer!
V = 16 cubic units
Example 2) A toy chest is shaped like a cube. It measures 2 feet, by 2 feet, by 2 feet. What is the volume of the toy chest?
Step 1: a picture! Step 2: your dimensions on the figure’s picture. (What units does the problem give you? )Step 3: your SFS = Shape, Formula, Substitute for the problem using the given dimensions. Shape: Formula: Substitute: Step 4: your dimensions.Step 5: Box your answer and write the correct for your answer!
