using Pythagoras theorem
x²=25+25=50
x=underoot 50
I have taken x as a side
since its diagonal is same.So, I have used Pythagoras theorem
underoot 50 is the answer

x=underoot 50

Hey!
Given,
Diagonal of cube = 10 cm
We know,
Pythagoras Theorem,
H² = P² + B²
10² = a² + a²
10² = 2a²
50 = a²
√50 = a
√25.5 = a
5√2 = a
Hence side of square = 5√2
