The length of the diagonal support is 69 feet.
Step-by-step explanation:
Dimensions of the box: length = 6 feet
width = 5 feet
height = 8 feet
The diagonal support relates with the diagonal of the base and the height.

=
+
=
+
= 36 + 25
= 61
x =
= 7.81
let the length of the diagonal support be represented by l. So that;
=
+
=
+
= + 64
l =
= 61 + 8
= 69
Thus, the length of the diagonal support is 69 feet.
