volume of wooden block/volume of each plank gives the number of planks we can obtain from the wooden block
wooden block and plank resembles cuboid
volume of cuboid = l*b*h
l= length
b= breadth
h= height
Volume of wooden block = 6*0.15*0.4
Volume of plank = 2*0.025*0.04
no of planks that can be obtained are
6*0.15*0.4/2*0.025*0.04
0.36/0.002=180
hence you can obtain 180 planks in total
