Let x bet the cases in favor of 5.
Number of cases in favor of 6=x
Then according to question
Number of cases in favor of 1=3x
Number of cases in favor of 2=3x
Number of cases in favor of 3=3x
Number of cases in favor of 4=3x
Sum of total cases=
Probability of getting 5 =
Probability of getting 1=
1.We have to find probability should be assigned to rolling a 4.
The probability of getting =
2.We have to find the probability of rolling 6.
The probability of getting 6=
The surface area of the three dimensional solid is 72 square centimeters and its three dimensional diagram is attached.
Step-by-step explanation:
The given is,
Detailed view or net diagram of the three dimensional diagram.
Step:1
Three dimensional diagram of the given net diagram is attached.
From the three dimensional diagram given net diagram is rectangular prism.
Step:2
From the three dimensional diagram
Formula for surface area of the rectangular prism,
..............................(1)
Where, w - Width
l - Length
h - Height
From the attachment,
l = 6 cm
w = 2 cm
h = 3 cm
Equation (1) becomes,
= 2 ( 12 + 18 + 6 )
= 2 ( 36 )
A = 72 squared centimeters
( or )
From the net diagram,
Surface area, A = ((6×3)+(2×3)+(2×6)+(2×3)+(3×6)+(2×6))
= 18 + 6 + 12 + 6 + 18 + 12
= 72
Surface area, A = 72 squared centimeters
Result:
The surface area of the three dimensional solid is 72 square centimeters and its three dimensional diagram is attached.
