It depends on the prism. Is it a triangular prism, a rectangular prism, a pentagonal prism... etc..
It is 94 square centimetres.
The lengths of the sides does not provide enough information to answer the question.
The equation for the surface area of a rectangular prism is: A = 2lw + 2lh + 2wh Replace the variables you know, and solve for the remaining variable.
15 cm
Rectangle area easiest math for area: 5cm X 3cm = 15cm2
It is 94 square centimetres.
5*3*4 = 60 cm3

i need help
For it to be a right angle triangle the 3rd side must be 5cm
Oh, dude, let me break it down for you. So, a centicube is a cube with sides that are 1 cm long. To fill a 3cm by 4cm by 5cm cube, you'd need 3 x 4 x 5 = 60 centicubes. That's like a whole bunch of tiny cubes fitting into a slightly bigger cube.
5cm
5cm
Mean = sum(X)/n = 15cm/5 = 3cm
The lengths of the sides does not provide enough information to answer the question.
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.
You cannot, because you have no information on the shape: is it a 2-d triangle or a 3-d cuboid?
