Final answer:
The height of the drawing of Ant-Man is 18 inches.
Step-by-step explanation:
To find the height of the drawing in inches, we need to use the scale given in the question. The scale is 3 in: 1 ft, which means that for every 3 inches on the drawing, it represents 1 foot in real life. Since Ant-Man is 6 feet tall, we can use this scale to find the height of the drawing.
If Ant-Man is 6 feet tall, we can set up a proportion to find the height of the drawing. Let x represent the height of the drawing in inches. Then, we have the proportion 3/1 = x/6.
Cross-multiplying, we get 1*x = 3*6. This simplifies to x = 18 inches. Therefore, the height of the drawing is 18 inches.
