Answer:
The density of the rectangular box is 0.8 g/mL.
Step-by-step explanation:
The density of an object is calculated by dividing its mass by its volume. In this case, the given mass of the rectangular box is 200g. To find the volume of the box, we need to multiply its length, width, and height.
Given dimensions of the rectangular box:
Length = 10 cm
Width = 5 cm
Height = 5 cm
To find the volume:
Volume = Length x Width x Height
Volume = 10 cm x 5 cm x 5 cm
Volume = 250 cm³
Now that we know the mass (200g) and volume (250 cm³) of the box, we can calculate its density:
Density = Mass / Volume
Density = 200g / 250 cm³
To simplify the units, we can convert cm³ to mL (milliliters) since they are equivalent:
1 cm³ = 1 mL
Density = 200g / 250 mL
Simplifying further:
Density = 0.8 g/mL
Therefore, the density of the rectangular box is 0.8 g/mL.
