<h2>Answer:</h2>
The probability of first drawing a girls name and then a boys name from the hat is:
It is given that:
The names of nine boys and two girls are in a hat.
This means that the total number of names in the hat are: 9+2=11.
Also, the probability of first drawing a girls name and then a boys name from the hat is given by:
Probability of drawing a girl name×Probability of drawing a boy name.
Also, the drawing of names is done without replacement.
Hence, we get probability as:
The probability is:

72 cubes
Step-by-step explanation:
Attached is the picture drawn (though not great one), showing 6 cube on length of prism, 3 cubes on width and 4 cubes on height of prism.
Given: Length of prism= 6
Width= 3
Height= 4
To know the number of cubes, which can fill the entire prism, we need to find volume of prism.
∴ Volume of prism=
Volume of prism=
∴ 72 units of cube can fill the entire prism.
