Cuboid - edges

The sum of all edges cuboid are 8 meters. However, the width is twice shorter than the length and height is seven times longer than the width. Determine the dimensions of the cuboid.

Result

a =  0.8 m
b =  1.6 m
c =  5.6 m

Solution:


a+b+c = 8
a = b/2
c = 7a

a+b+c = 8
2a-b = 0
7a-c = 0

a = 45 = 0.8
b = 85 = 1.6
c = 285 = 5.6
