Answer:
1/3 kg/m3
Step-by-step explanation:
density= mass/volume
mass=40 kg
volume=5m×8m×3m=120m³
density=40kg/120m³=1/3 kg/m³
Answer:
1/3 kg per cubic m or 0.33kg per cubic m
Step-by-step explanation:
density = <u>mass</u>
volume
= <u> 40kg </u> = <u>40kg</u>
5m x 8m x 3m = 120cubic metres
= <u>1/3 kg per cubic m or 0.33 kg per cubic m</u>
