45 grams is about 1/4 cup of water or maybe 1/4 cup of flour or uncooked rice would be 45 grams. Anyway it's not much.
Unless the dresser is made of paper, 45 grams is not enough. 45 kg though large (that's roughly 100 pounds if that's what you think in), the dresser might be found in the apartment where Sherlock Holmes lives. (The dresser is a piece of victorian furniture) it is much closer to what a modern dresser would weigh.
To find median, you must first order the numbers from least to greatest.
$3.85, $4.79, $4.85, $5.38, $5.96
Since there is an odd amount of numbers, the median is the middle number.
In this case, the number in the middle is $4.85.
This means that the median is $4.85.
Hope this helps!
