I am not sure what the point is for you to give us the dimensions of a rectangle and then ask what one of those dimensions is. Perhaps you are not sure whether the shorter or the longer of the two dimensions would be considered the length, and which the width. I would say that a rectangle measuring 2cm x 5cm is 2cm wide and 5cm long.
No because to form a triangle the sum of its smallest sides must be greater than its longest side.
A rectangular prism that measures 8.2cm 5cm and 2cm has a volume of 82cm3

The volume is 3cm * 2cm * 5cm = 30 cm3. The density will depend on the mass of the prism which will depend on the material that the prism is made from.
What is the area of a triangle with base 2cm and height 3cm
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
5cm 2cm
5cm x 2cm x 6cm = 60 cubic cm.

2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
5cm, 5cm, and 5cm could represent the lengths of the sides of an equilateral triangle, or might indicate the length, width, and height of a cube.
In order to find the area of a rectangle, multiply the length by the width of the rectangle. For example: If the length of a rectangle is 5cm and the width of a rectangle is 2cm, then the area of the rectangle would be 5cm X 2cm = 10cm².
The area of a rectangle is given by the formula: length x width. So, for the textbook, the area would be 5cm x 2cm = 10 square cm.

No. It is not possible, because a triangle cannot have a side longer than the sum of two other sides. 5 is greater than 2+2. Therefore the triangle cannot exist.
