Objective:
Students understand volume and can derive the formula for volume of rectangular prisms.
Separate students into groups of four. Give each group of students 24 cubic units and instruct them to build or draw as many rectangular prisms as they can given n cubic units. List the factors of each volume number.
Example: 6 cubic units

Formulas
|
1) 24 cubic units
2) 9 cubic units
3) 16 cubic units
4) 8 cubic units
5) 13 cubic units
Extra:
|
The area of a rectangle is(base x height) and the area of a triangle is 1/2 x base x height.
|
|
If the volume of a rectangular prism is (length x width x height), then what do you suppose is the volume of a triangular prism?
