Answer:

24 buckets

Step-by-step explanation:

Dimension of rectangular block = 45 m by 38 m

A bucket of paint will cover 72m² of floor

Total area of floor : Length * Width

Total Area = (45m * 38m) = 1710 m²

Buckets of paint required :

Total area / Area per bucket

= 1710m² / 72m²

= 23.75 buckets

= 24 buckets
