A cube with side length 5h^2 is stacked on another cube with side length 3k What is the total volume of the cubes in factored form? |
|
Answer» The first one : (5h²)³ The second one: (3k)³ ADD them together: (5h²)³ + (3k)³ Since you now have the sum of two cubes, you can FACTOR it as: x³ + y³ = (X + y)(x² - xy + y²) SUBSTITUTE 5h² for x and 3k for y to get: (5h² + 3k)((5h²)² - 5h(3k) + (3k)²) |
