The value of the ratio of isometric length to true length is
a) 0.141
b) 0.372
c) 0.815
d) 0.642
Answer: c
Explanation:
If we represent a cube in isometric view the diagonal of upper face of cube is equal to the true length of the diagonal. From it by drawing an actual square around it and then calculating
it gives (1/cos 30)/ (1/cos 45)
=isometric /true
=0.815.
