Bill's rectangular bedroom is 2 m long, 4 m wide, and 2.5 m high. Air typically has around 4,000 bacteria per cubic meter. About how many bacteria are present in Bill's bedroom?

80000bacterias

Step-by-step 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
