Solution

Volume of box $= (200 \times 25 \times 8) c m^{3}$ $= 40000 c m^{3}$

Volume of wood $= (500 \times 70 \times 32) c m^{3}$ $= 1120000 c m^{3}$

(courting all to is)
No.of planks $= \frac{v o l u m e o f w o o d}{v o l u m e o f b o x} = \frac{1120000}{40000}$ $= 28$

No. of plants that can be prepared from the
wooden block is $28.$
