20 and 30 are rectangular numbers (4 * 5 and 5 * 6). There are none in between them.
Rectangular numbers, also known as oblong numbers or pronic numbers, are the product of two consecutive integers. The rectangular numbers between 2 and 40 are 6 (2×3), 12 (3×4), 20 (4×5), 30 (5×6), and 42 (6×7). However, since 42 exceeds 40, the rectangular numbers between 2 and 40 are 6, 12, 20, and 30.
There is an infinite number of numbers between 0 and 20.
There are an infinite number of 3d shapes with more than 20 faces.
The only square number between 20 and 30 is 25.

The question is: What is a Composite number between 10 and 20. First we must remember that a Composite number is a number that is divisible by itself, 1, and also another is considered a Composite number. Therefore, the Composite numbers between 10 and 20 are 10, 12, 14, 15, 16, 18 and 20. The other numbers are called Prime numbers.
