Answer:

13.9 inches

Step-by-step explanation:

Let the length of diagonal of cube be d inches.

$\therefore \: d = length \: of \: side \sqrt{3} \\ \hspace{16 pt} = 8 \sqrt{3} \\ \hspace{16 pt} =8 \times 1.73205081 \\ \hspace{16 pt} = 13.8564065 \\ \huge \red{ \boxed{\therefore \: d = 13.9 \: inches }}\\$

Answer:

Step-by-step explanation:

We will use two properties to solve this problem,

1). Medians of a triangle bisect the sides of a triangle.

2). Centroid of a triangle divides the medians in the ratio of 2 : 1.

Length of FH = 2 × Length of HX

= 2 × 12

FH = 24
