Answer:

[tex]4\sqrt{\pi}[/tex]

Step-by-step explanation:

  • The cross section of a sphere is a circle with area  [tex]\pi r^2[/tex], where radius is given as 4
  • The cross section of the cube is a square with area  [tex]a^2[/tex], where a is side length of square

The circle area = the square area. Thus we have:

[tex]\pi r^2 = a^2 \\\pi(4)^2=a^2\\16\pi=a^2\\\sqrt{16\pi}=a\\ a=\sqrt{16} \sqrt{\pi} \\a=4\sqrt{\pi}[/tex]

Answer:

your answer would be 4\sqrt{\pi}
