I am really bad at math. I am more of a comprehensive essay writer.
Regardless, I tried and I think to the length of the cube is roughly 2.05 for the volume and 1.45 for the surface area if I did my math right (I rounded to the second place).
Close! Not quite though.
You got the surface area correct! But the volume you're a bit off
Volume of a sphere is given as (4/3)*Pi*r
3, which for a unit sphere is just (4/3)*Pi. Volume of a cube is given as a
3. So we solve the equation a
3 = (4/3)*Pi or a = cubeRoot((4/3)*Pi) ~= 1.66
