Chad bought a bag of Lego blocks. He made three cars using 7 Lego blocks for each car. When he was done. He had 22 Lego blocks left. How many Lego blocks came in the bag he bought?

Chad used a total of 21 Lego blocks to make three cars (3 cars x 7 blocks each = 21 blocks). Since he has 22 blocks left, we can add the blocks used to those remaining to find the total. So, 21 blocks (used) + 22 blocks (remaining) = 43 blocks. Chad's bag originally contained 43 Lego blocks! Did you know that Lego was invented in Denmark in 1932? It started as a wooden toy company before transitioning to the iconic plastic bricks we know and love today. The name "Lego" comes from the Danish phrase "leg godt," which means "play well." In the world of Lego, creativity knows no bounds! One common mistake is not keeping track of your pieces as you build. It can be easy to lose track when you're assembling your masterpiece. To avoid frustration, try organizing your blocks by color or size before you start building. It makes finding those elusive pieces much easier and keeps your building experience fun!
