Wall and body diagonals

Calculate the lengths of the wall and body diagonals of the cuboid with edge dimensions of 0.5 m, 1 m, and 2 m

Correct answer:

u1 =  1.118 m
u2 =  2.0616 m
u3 =  2.2361 m
d =  2.2913 m

Step-by-step explanation:

a=0.5 m b=1 m c=2 m  u1=a2+b2=0.52+12=1.118 m
u2=a2+c2=0.52+22=2.0616 m
u3=b2+c2=12+22=5=2.2361 m
d = a2 + b2 + c2  d=u12+c2=1.1182+22=2.2913 m
