Respuesta :
IF the side length is 10cm , then the length of diagonal of the base of the cube(x) is X² =(10)²+(10)² =200cm so x = 10√2cm
so the length of diagonal of the cube(y) is
y² = (10)² + (10√2)² =300 so y =10√3cm
so the length of diagonal of the cube(y) is
y² = (10)² + (10√2)² =300 so y =10√3cm
