5th Grade Math 11.5, Unit Cubes & Solid Figures

Note: This is lesson 11.6 in the 2012 copyright. A unit cube is a rectangular prism that is 1 unit long, 1 unit wide, and 1 unit high. It has 6 square faces and 12 edges. We can use unit cubes to build rectangular prisms and other solid figures by joining or stacking the unit cubes. To build a rectangular prism, each row needs to have the same number of unit cubes. A rectangular prism will have 6 faces, no matter how many unit cubes it is made of. A rectangular prism has the same number of edges as a unit cube. All rectangular prisms can be made up of unit cubes. Unit cubes are special rectangular prisms with faces that are squares, and the size of the unit can change with the size of the figure. 1 unit might be 1 centimeter, 1 inch, 1 foot, 1 yard, 1 meter, etc. We compare the number of unit cubes in solid figures using less than, greater than, or equal to symbols. We count and write the number of unit cubes for each level of a solid figure. We find the length, width, and height of rectangular prisms in unit cubes.
