Question 8 Volume And Surface Area Of Solids Exercise 15A

A godown measure 40m × 25m × 15m. Find the maximum number of wooden crates, each measuring 1.5m × 1.25m × 0.5m that can be stored in the godown.

It is given that

Length of the godown = 40m

Breadth of the godown = 25m

Height of the godown = 15m

We know that

Volume of godown = l × b × h

By substituting the values

Volume of godown = 40 × 25 × 15

On further calculation

Volume of godown = 15000 m3

It is given that

Length of wooden crate = 1.5m

Breadth of wooden crate = 1.25m

Height of wooden crate = 0.5m

We know that

Volume of each wooden crate = l × b × h

By substituting the values

Volume of each wooden crate = 1.5 × 1.25 × 0.5

On further calculation

Volume of each wooden crate = 0.9375 m3

So we get

Number of wooden crates that can be stored in godown = Volume of godown/ Volume of each wooden crate

By substituting the values

Number of wooden crates that can be stored in godown = 15000/ 0.9375

So we get

Number of wooden crates that can be stored in godown = 16000

Therefore, the number of wooden crates that can be stored in the godown are 16000.
