Volume with Fractions
Opening exercise:
How many 1 x 1x 1 inch cubes will fit across the bottom of the first rectangular prism? How many layers of 1 x 1 x 1 inch cubes would fit inside the prism?
Volume of first prism = Volume of second prism =
Which prism holds more cubes? How many more cubes does the prism hold?
Example 1
How many dice (½ inch) can fit in the box?
V = l x w x h
V = 10 x 4 x 6 = Example 2
How many ¼ inch cubes can fill the prism?
1. Find the volume V = 1 ½ x 1 x 3 ¾
V = 2. Find volume of ¼ inch cubes =
3. How many cubes will fit into the prism?
