Good afternoon!
We calculate the volume of the container in cm³. To do that, we must put the units in cm:
30 cm → 30 cm
50 mm → 5 cm
0.2 m → 20 cm
The volume is:
V = 30 . 5 . 20
V = 3000 cm³
Now, we calculate the mas with the formula:
m = dV
m = 2.5 · 3000
m = 7500 g
Dividing by 1000, we have the mass in kg:
m = 7.5 kg
Maps and Globes share the following features:
Both are scale Models.
Explanation:
A globe is a scale model of the Earth that presents the most accurate depiction of geographic information such as area, distance, and direction.
A map is a two dimensional representation or a drawing of the earth’s surface, or a part of it, on a flat surface, according to a scale. Thus it is also a scale model.
A globe differs from a map. It is a three dimensional sphere representing the whole Earth.
A map is usually used to represent a specific part of the Earth and is used for Navigation. It has details and symbols. However, a globe can not be used for such details.
A globe can be used to get a broad-level picture of the world.
