Question

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

Answer 1

Answer:

THE ANSWER IS 768

Step-by-step explanation:

The dimension of the plank are

Length =5m=500cm

Breadth =25cm

Height =10cm

We know that

Volume of the plank =1×b×h

By substituting the values

Volume of the plank =500×25×10

So we get

Volume of the plank =125000 cm

The dimension of the pit are

Length =20m=2000 cm

Breadth =6m=600 cm

Height =80cm

We know that

Volume of one pit =1×b×h

By substituting the values

Volume of one pit =2000×600×80

Volume of one pit =9600000cm

3

So the number of plank that can be stored = Volume of one pit /Volume of plank

Number of planks that can be stored =

125000

9600000

​Number of planks that can be stored =768
