Question

Read the above attachment and answer it ​

Answer 1

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.
