Can you explain how to solve this math problem: Adam owns a wood carving shop, if a block of basswood can create 3 figurines and a block of butternut wood can create 4 figurines, and a block of Aspen wood can make twice the amount of figurines compared to basswood, how many figurines can he make if he owns 15 blocks of basswood, 20 blocks of butternut wood, and 20 blocks of Aspen wood?
