Question

volume of a cube below is
$2 \sqrt{2}$
Find the radius of a circle containing one side of a cube.​

Answer 1

√2/2

Step-by-step explanation:

volume of cube = 2√2 (given)

a^3 = 2√2 => a = (2√2)^1/3

= (2^1 ×2^1/2)^1/3 = [({2^(1+1/2)}]^1/3

= 2^(3/2×1/3) = 2^1/2 = √2

radius of circle = a/2 = √2/2
