If one pot of paint covers an area of 5m2. How many pots will be needed to cover the floor?

Answer: 2 pots
Step-by-step explanation:
area of the floor = length x width
= 400 cm x 250 cm
= 100 000 cm²
5 m² = 5 x 10 000 cm² = 50 000 cm²
number of pots needed = area of floor ÷ area covered by one pot
= 100 000 cm² ÷ 50 000 cm²
= 2 pots
