Question

If the side of a cube be 'a' unit and diagonal of the cube be 'd' then relation
between a and d is..... (a) v2a=d (b) v3a=d (c) a=v3d (d) a=v2d​

Answer 1

Answer:

Given: side x = 5 cm

Use diagonal formula,

Diagonal of cube = 3–√x

Diagonal of cube = 3–√∗5

We know that the value of √3 is 1.734

Therefore, the diagonal of a cube = 1.734 (5)

Diagonal of cube = 8.67 cm
