Answer: 180 planks
Step-by-step explanation:
the length of plank = 200 cm
breadth of plank = 2.5 cm
height of plank = 4 cm
so, the volume of one plank = l×b×h
= 200×2.5×4
= 2000 cm³
length of wooden block = 600 cm
breadth of wooden block = 15 cm
height of wooden block= 40 cm
so, volume of wooden block = l×b×h
= 600×15×40
= 360000 cm³
thus, no. of planks cut = 360000÷2000
=180 planks

no problem.
