You Can Multiply Three Numbers in Any Order

Illustrative MathematicsVaries

The purpose of this task is for students to use the volume of a rectangular prism to see why you can multiply three numbers in any order you want and still get the same result. Formally, this is a consequence of the commutative and associative properties of multiplication. While not one of the field axioms, some people call this the any-order property of multiplication because we can multiply three numbers in any order and get the same product.
