Acube 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?

(5h^2 + 3k)(25h^4 - 15h^2k + 9k^2)

Step-by-step explanation:

So, the formula for the volume(V) of a cube is V = a^3, where "a" is the length of one side. This is because, on a cube, each side/edge is the same length. (Just to clarify)

Now, the side of one cube is 5h^2. If you cube this value, you get (5h^2)^3. That is the volume of this cube.

Do the same with the other. 3k cubed = (3k)^3

Because this is an addition problem, you will be adding the values:

(5h^2)^3 + (3k)^3

To factor, you can use the sum of cubes formula:

a^3 + b^3 = (a + b)(a^2 - 2ab + b^2)

*Make sure you pay attention to the negative sign!

After plugging it all in and simplifying, you should get

(5h^2 + 3k)(25h^4 - 15 h^2k + 9k^2)

Hope I helped!

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
