Body: <p>In the LEGO Super Mario app, they have created some neat looking bases, however they have a lot of complicated slopes and smooth plates. It's clearly a 3D model, but it looks as though as if it could theoretically be created using available LEGO parts. I can't seem to figure out how to make a slope on a 45 degree angle though. It looks like the base has 65-degree angled slopes which would be totally impossible using available parts, but if you were to build this using <em>45-degree</em> slopes, you wouldn't want to use 3045 to corner it on the left side, you'd want to use some kind of angled part at the corner. I was curious to know if the following is even possible:</p>

  A 45 degree slope doesn't fit the standard geometry of the LEGO system.
  
  The basic "3D module" of the system (a 1x1 plate) is 5 units square by 2 units tall.
  
  A brick is three plates tall - i.e. 5 units square by 6 units tall.
  
  Therefore, the smallest *perfect cube* you can build is 6 bricks square by 5 bricks tall. It should be clear that can't be split into two "wedges" or "cheese pieces" with 45 degree slopes.
  
  The 2x2 wedge piece in username_2's answer, and all the other 45 degree slope brick parts, work round this by having a small vertical base under the 45 degree sections to make them one brick tall, and therefore they are not stackable to make a *smooth* 45 degree slope. If you do stack them, the "average slope" is close to 50 degrees, not 45.

  At a small scale the part [Wedge 2 x 2 (Slope 45 Corner)](https://www.bricklink.com/v2/catalog/catalogitem.page?P=13548#T=C) could do this, but this approach can't be scaled up:
