Answer:-
(2) 12 cm
Explanation:-
It is given that the side of cube is 12 cm. If we connect 3 such cubes we will see that the length of the cuboid will be tripled but its breadth and height will remain the same. Hence, its height is 12cm.

Answer:
1) 36cm
Step-by-step explanation:
v.of .cube=v.of .cuboid eq 1
a^3=l×b×h
gn:
cube a=12cm. cuboid l×b= 144
3 cubes ,
v.of one cube=1728
". ". 3. ". =1728×3
=5184
by eq 1
5184=l×b×h
5184=144×h
5184÷144=h
h=36
