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.
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.
30 ( cm x cm )
The perimeter is the total distance around a two-dimensional shape. To find the perimeter of a shape, you need to add up all the lengths of its sides. In this case, the perimeter of a shape with sides measuring 5cm and 2cm would be 5cm + 5cm + 2cm + 2cm = 14cm.

maybe its uhm 24mm?
5cm x 2cm x 6cm = 60 cubic cm.
2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
32.56
Oh, dude, let me break it down for you. So, 2cm is the same as 20mm, right? And if 4mm is a part of that 20mm, then the fraction would be 4/20, which simplifies to 1/5. So, 4mm of 2cm is like 1/5. Easy peasy, right?
