Cube Model for (a+b)^3
thingiverse
Human: Cube Model for (a+b)^3 Visual or physical models are not always necessary in learning algebra, but they can still be useful tools. Some students and adults alike find it helpful to see the physical connections of abstract mathematics, such as expanding (a+b)^3. After using a visual model, it is less likely that they will write (a+b)^3 = a^3 + b^3. The cube design presented here has dimensions: a=38mm and b=12mm, with an assembled cube measuring 50mm. To simplify the complexity of the model, I combined b^3 with 3ab^2 into one piece. To fully understand the meaning of each component, we need to discuss them together.
