Answer:
Vol if the plank= l.b.h
= 4m×5cm×4cm
converting into meters
= 4m×0.05m×0.04m
= 0.20m²× 0.04m
= 0.008m³
Now vol of the wooden block
= l.b.h
= 12m× 30cm×80cm
converting into m
= 12m × 0.3m× 0.8m
= 3.6m²× 0.8m
= 2.88m³
No. of planks that can be cut out = vol of box/vol of plank
= 2.88m³/0.008m³
= 2880/8= 360
or
12m×30cm×80cm/4m×5cm×4cm= 3×6×20= 360.
