There are more than you think ;) There is no limit to shapes, everything comes in shapes and sizes. For example, A computer has soft edges and it is rectangular. Peole can make up shapes if they want to, But more the merrier!
There are an infinite number of shapes, because a shape can have any number of sides. This is where we get into our laws of fractals. A fractal is a shape with an infinite perimeter and area, meaning that every level of infinity is another shape, but can be beat by another shape. However, this is all philosophical math and goes way beyond the context of your question.
To keep it short and simple, there are an infinite number of shapes in the world.
Hi there! An average person ate 200.8 pounds of meat, so we would multiply that number by 3 to see how much meat the family ate altogether. 200.8 * 3 is 602.4. There. A family of 3 would eat 602.4 pounds of meat in a year.
