Abigail because that's what I think would be the best but I wouldn't trust me on that cause I'm just guessing
We know that the side lengths of the square base are: x * x. The volume is 12, so for now, let's say that y is the other side length. Then, x * x * y = 12. We can solve for y: y = 12/x^2. Now, we find the surface area of the 5 sides.
Four of the sides have the same area: x * (12/x^2) = 12/x, so we multiply this by 4: 48/x.
The last side is the base: x * x = x^2.
We add 48/x to x^2:
x^2 + 48/x
So, the answer is the fourth choice, (d).
Answer:
D.
Step-by-step explanation:
Simply plug in your variables and solve (<em>r </em>= x + 2 and <em>h</em> = 3x + 8):
V = π(x + 2)²(3x + 8)
V = π(x² + 4x + 4)(3x + 8)
V = π(3x³ + 20x² + 44x + 32)
V = 3x³π + 20x²π + 44xπ + 32π
