A number greater than 2 is: 3, 4, 5, 6
Roll 1: 4 numbers out of 6 numbers total = 4/6 = 2/3
Roll 2: (same as roll 1)
Roll 3: (same as roll 1)
Roll 1 AND Roll 2 AND Roll 3
2/3 x 2/3 x 2/3 = 2³/3³ = 8/27

Answer:
So your answer according to these hints I provided for you, should lead you to your answer, which should in other words be,
The 1st. The 2nd. And I would say...The 4th. The reason why I say not the 3rd one is because the 4 has nothing to do with the 8, the 3 does because it's divided by it.
If it's not useful, feel free to report for mistake in answer. -_-
Answer:
The dimension of the open rectangular box is .
The volume of the box is 8.217 cubic inches.
Step-by-step explanation:
Given : The open rectangular box of maximum volume that can be made from a sheet of cardboard 11 in. by 7 in. by cutting congruent squares from the corners and folding up the sides.
To find : The dimensions and the volume of the open rectangular box ?
Solution :
Let the height be 'x'.
The length of the box is '11-2x'.
The breadth of the box is '7-2x'.
The volume of the box is
Derivate w.r.t x,
The critical point when V'(x)=0
Solve by quadratic formula,
Derivate again w.r.t x,
Now, (+ve)
(-ve)
So, there is maximum at x=1.392.
The length of the box is
The breadth of the box is
The height of the box is h=1.392.
The dimension of the open rectangular box is .
The volume of the box is
The volume of the box is 8.217 cubic inches.
