Question

the maximum length of a rod that can be kept in a Cuboidal box of dimension 12cm×9cm×8cm is​

Answer 1

Answer:17cm

Step-by-step explanation:

√a²+b²+c²  =   √12²+9²+8    =   √144+81+64   =  √289   =  17cm  

Answer 2

Length of rod=diagonal of the cuboid

Step-by-step explanation:

Dimensions=12cm*9cm*8cm

Length=12cm

Breadth=9cm

Height=8cm

Diagonal=root l^2 +b^2+ h^2

L^2=144,b^2=81,c^2=64

Therefore diagonal=root 144+81+64

=root 289=17cm

Therefore,Length of rod is 17cm.
