How does indina decide how much sand to keep in the bag

In the movie "Raiders of the Lost Ark," there is a scene where Indiana Jones needs to replace a golden idol with a bag of sand in order to prevent a trap from being triggered. To answer your question, let's break it down step by step:

1. How does Indiana decide how much sand to put into the bag?
Indiana Jones decides to put sand into the bag based on his estimation and observation. He evaluates the weight and volume of the golden idol in his hand.

2. What does he appear to be doing?
In the movie, it appears that Indiana Jones is visually and physically gauging the weight of the golden idol by lifting it and feeling its density. He is essentially trying to find a suitable substitute that will match the weight of the idol.

3. What assumption is he making?
Indiana Jones is assuming that the bag of sand he puts in as a replacement will weigh roughly the same as the golden idol. The assumption is that the mechanism triggering the trap is based on weight, and by replacing the idol with a similarly weighted object, he can avoid activating the trap.

It's important to note that this scene is fictional, and in real-life situations, estimating weight accurately can be challenging. It is typically better to use a scale or measure the weight directly to ensure accuracy.
