Answer:

80000bacterias

Explanation:

Volume of the bedroom= length ×width× height

Given

Length = 2m

Width = 4m

Height= 2.5m

Volume of the bedroom= 2×4×2.5

Volume of the bedroom = 20m³

Given that;

4000bacterias = 1m³

x bacteria = 20m³

Cross multiply

x =4000×20

x =80000

Hence 80000 bacteria's are present in Bill's room
