Answer:The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height. The formula A=lw is used to find the area of the three rectangular side faces, where A = area, l = length, and w = width.
Plugging in the measurements that are given in the net, calculate the area of each face. Remember to use the correct area formula for the triangles
Answer:
Probability of sum of pips on two faces is at least 9 = 
Step-by-step explanation:
Experiment: Throwing two fair dice.
Total no of Outcome =
= 36
Sample space (list of outcome) is attached.
Let E be the event that sum of pips on two faces is at least 9.

Favorable outcome are where sum is 9 , 10 , 11 and 12.
From Sample space, No. of Favorable outcome = 10
∴ 

The value of this equation is: 4
Answer: 4
