Step-by-step explanation:
1. Approach
The surface area is the two-dimensional space around a three-dimensional object. In other words, if one was going to wrap an object with paper, the surface area is the amount of paper one would need. To find the surface area, one could find the area of each face of the prism and then add up all of the values.
2. Finding the surface area,
To find the area of each face of the prism, one must multiply the length of the face by the width of the face. After doing so, add up all of the resulting values.
10 * 20 = 200
8 * 20 = 160
6 * 20 = 120
* 6 * 8 = 24
* 6 * 8 = 24
Add up all of the values,
200 + 160 + 120 + 24 + 24
= 528

Answer:
1440
Step-by-step explanation:
We can solve this problem by applying the rule of three.
In fact, we know that:
- Over a package of 210 candies,
- The number of brown candies is 63
- Here we want to find what is the number of brown candies when the total number of candies contained in the package is 4800
So we can set up the following rule of three:
where
x = number of brown candies when the total number of candies contained in the package is 4800
Solving the expression for x, we find:
So, Sarah can expect to find 1440 brown candies in a package of 4800 pieces.
