A rectangular box has length 2 inches, width 8 inches, and a height of 10 inches. Find the angle between the diagonal of the box and the diagonal of its base. The angle should be measured in radians.

a) diagonal box = 12.9 in

b) diagonal base = 8.2 in

Step-by-step explanation:

w = 8 in

h = 10 in

L = 2 in

required:

a) diagonal of the box

b) diagonal of its base

referring into the attached image

a) the diagonal of the box = sqrt ( w² + h² + L²)

  diagonal box = sqrt (8² + 10² + 2²)

  diagonal box = 12.9 in

b) diagonal of its base = sqrt ( w² + L²)

   diagonal base = sqrt ( 8² + 2²)

   diagonal base = 8.2 in
