A bucket can hold 6.25 liters of water. How many such buckets are needed to fill a 1 cubic meter tank?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 160.
Bucket holds 6.25 liters = 6.25 × 10-3 m3
Tank volume = 1 m3
Number of buckets = 1/(6.25 × 10-3) = 1000/6.25 = 160
