May you guys help me understand "rectangular prism"?
I read and read, but I still don't understand it.
Please, thanks.
Is there anything specific that you don't understand about it?
A rectangular prism is basically like a cube, except all of the sides can be rectangles.
Common name: a box
As you can see in this web site, a rectangular prism is a box -- like a tissue box, or cereal box.

rectangular prism is box with 6 faces
where the surface area is a=2((width*height)+(length*width) +(length*height))
and the volume is v=Lenght*width*height
Okay, thank you.
Of course! I'd be happy to help you understand what a rectangular prism is.
A rectangular prism is a three-dimensional geometric shape that has six faces, all of which are rectangular. It is also known as a rectangular cuboid or simply a cuboid. The term "prism" refers to any three-dimensional shape that has flat faces and identical cross-sections parallel to the base.
To better understand a rectangular prism, let's break down its characteristics:
1. Faces: A rectangular prism has six faces. All the faces are rectangles, which means they have four sides and four right angles.
2. Edges: A rectangular prism has 12 edges. These are the line segments where two faces meet.
3. Vertices: A rectangular prism has eight vertices (also known as corners). These are the points where three edges meet.
4. Dimensions: A rectangular prism has three dimensions: length, width, and height. The length refers to the longest side, the width is the shorter side, and the height is the vertical distance between the top and bottom faces.
To visualize a rectangular prism, imagine a shoebox or a brick. These objects are good examples of rectangular prisms.
To find the volume of a rectangular prism, you need to multiply the length, width, and height together. The formula for volume is V = length × width × height.
To find the surface area of a rectangular prism, you can add up the areas of all six faces. If the length, width, and height are denoted as L, W, and H respectively, then the formula for surface area is SA = 2(LW + LH + WH).
I hope this explanation helps clarify what a rectangular prism is! Let me know if you have any further questions.
