We connect dots with toothpicks in a grid as shown below. The grid below has 5 horizontal toothpicks in each row and 5 vertical toothpicks in each column.
 

Suppose we instead have a grid of dots that requires 10 horizontal toothpicks in each row and 20 vertical ones in each column. Then, how many total toothpicks will we need?
