Detailed Solution

It is given a cuboid of length 1.2 m, breadth 30 cm and height 15 cm.
The formula used in solving this problem is,
Volume of the cuboid, V=l×b×h   Here, l is length, b is breadth and ‘h’ is height.
Here,
Length of the cuboid,
l =1 .2 m ⇒l=1.2×100 ⇒l=120 cm                  (1m=100cm)
Breadth of the cuboid, b =30 cm
Height of the cuboid, h =15 cm
Volume of the cuboid,
V=l×b×h  
⇒V=120 cm×30cm×15 cm  
⇒V=54000 c m 3                              The volume of the required cuboid is V=54000 c m 3   .
Hence option (3) is correct.
