It is given that the perimeter of the cuboid is 26cm
Length = L
Breadth = B
Height = H
2L + 2B = 26
L + B = 13
As seen from the factors of 324, L x B x H = 324
L + B must also be 13.
Hence, 6 x 6 x 9 is not valid as the following L + B won’t give you 13cm.
The only possible one is 4 x 9 x 9.
Given so, Length = 9cm, Breadth = 4cm.
324/(4x9) = 9
Height is 9cm
