Cuboid face diagonals

The lengths of the cuboid edges are in the ratio 1: 2: 3. Will the lengths of its diagonals be the same ratio?

The cuboid has dimensions of 5 cm, 10 cm, and 15 cm. Calculate the size of the wall diagonals of this cuboid.

Correct result:

y =  0

Solution:

a=5 b=10 c=15  a:b:c=1:2:3  u1=a2+b2=52+102=5 511.1803 u2=a2+c2=52+152=5 1015.8114 u3=b2+c2=102+152=5 1318.0278  k1=u1:u2=11.1803:15.81140.7071 k2=u3:u2=18.0278:15.81141.1402 k3=u3:u1=18.0278:11.18031.6125  k1,k2,k31,2,3  y=0
