Volume with fractional edge lengths
Calculate prism volume with fractional side lengths
Problem types
- Select true statements about a prism of fractional cubes
- Pack a prism with fraction cubes
- Volume with fractional edges
- Count, size, then check
Builds on
- Multiplying fractions
- Volume of a rectangular prism
- Volume in unit cubes · Earlier idea
Counting unit cubes extends to packing a prism with cubes of fractional edge length.
Leads to
- Area and volume of composite figures
- Modeling density · See it applied
Mass is density times volume, and volume of a prism with fractional edges gives the mass of a block.
- Volumes of cylinders, cones, pyramids, spheres · See it applied
Volumes of prisms with fractional edges are used to find volumes of composite solids in a modeling situation.
