Answer:
≈ 14.14 cm³
Step-by-step explanation:
First find the side length of the cube.
V=S³
27=S³
∛27=∛s³
3=S
Then the volume of the sphere.
V= × π(pi) × r³(radius cubed)
V= × π(pi) × (1.5³)
=π cm³ ≈ 14.14 cm³
Let s be the side length of the square. The dimensions of the rectangle are three times the side of the square (i.e. 3s), and two less than the side of the square (i.e. s-2).
So, the area of this rectangle is
The area of the square is , and we know that the two areas are the same, so we have
The solution s=0 would lead to the extreme case where the rectangle and the square are actually a point, so we accept the solution s=3.
