Question

How many planks of dimensions ( 5 m × 25 cm × 10 cm) can be stored in a pit which is 20 m long, 6 m wide and 80 cm deep?​

Answer 1

Solution:

Length of plank = 5 m

= 500 cm

Breadth of plank = 25 cm

Height of plank = 10 cm

Hence,

Volume = l × b × h

= (500 × 25 × 10) cm³

Now,

Length of pit = 20 m

= 2000 cm

Breadth of pit = 6 m

= 600 cm

Height of pit = 80 cm

Hence,

Volume = l × b × h

= (2000 × 600 × 80) cm³

∴ Number of planks that can be stored

= Volume of Pit / Volume of Plank

= (2000 × 600 × 80) / (500 × 25 × 10)

= 768
