Answer: 84 ft^2
Step-by-step explanation:
The whole prism can be divided into 5 surfaces.
Two triangles and 3 rectangles.
Find the area of each of the 5 shapes and add them together.
The triangle has a base of 4 and a height of 3.
Area of triangle 1: A= 4*3 * 1/2
A = 6
Area of triangle 2: A = 4*3 * 1/2
A = 6
Area of rectangle 1 : A= 4*6
A = 24
Area of rectangle 2; A = 3*6
A = 18
Area of rectangle 3: A= 5 *6
A = 30
Now add the areas together
6 + 6 + 24 + 18 + 30 + = 84 ft^2
Answer:
1320
Step-by-step explanation:
We are given that
Total number of athelets are running in race=12
Total number of medals =3
We have to find the total possible number of ways can the 3 medals be distributed.
Total number of ways for choosen gold medal=12
Number of ways for choosen silver medal=11
Number of ways for choosen Bronze medal=10
Total number of possible ways=
Hence, total number of possible ways in which 3 medals be distributed=1320
