Question

diagonal of a cube of edge x is ___ units

Answer 1

$\red{ \underline {\underline {\star \: { Answer:-}}}}$

$\longrightarrow \sqrt{3} x.$

Answer 2

Answer:

let X be the edge of cube then hypotenuse to adjacent edges are Y= x²+ x²

Y= 2x²

therefore, diagonal, z² = y² + x²

z²= x² + 2x²

z²= 3x²

z= √3 x
