A rectangular prism that measures 8.2cm 5cm and 2cm has a volume of 82cm3
A 2*2*2*2 has a triangular cross-section that has sides of 2 cm each. The area of cross section is sqrt(3). So the volume of the prism = 2*sqrt(3) = 3.464 cc (approx)
8 cm3 i hope this isn't for your homework

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.
height of triangle - 2cmbase of triangle - 10cmlength of prism - 10cmRemember, this is just one example I made up off the top of my head. There are plenty of others.
10x4x2= 80cm cube
