Question

. How many planks o dimension(5 m x25 cmx 10 cm) can be stored in a pit which is 20m long,6 m wide and 50 cm deep? *

Answer 1

Step-by-step explanation:

The dimensions of the plank are

Length = 5m = 500cm

Breadth = 25cm

Height = 10cm

We know that

Volume of the plank = l × b × h

By substituting the values

Volume of the plank = 500 × 25 × 10

So we get Volume of the plank = 125000 cm3

The dimensions of the pit are

Length = 20m = 2000 cm

Breadth = 6m = 600 cm

Height = 50cm

We know that

Volume of one pit = l × b × h

By substituting the values

Volume of one pit = 2000 × 600 × 50

So we get Volume of one pit =60,000,000cm3

So the number of planks that can be stored = Volume of one pit/ Volume of plank By substituting the values Number of planks that can be stored =60,000,000/125000

Therefore, the number of planks that can be stored is 480.
