Grade: 6-a Lesson: S3-L3 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Determine the surface area of the regular hexagonal prism if the height of the prism is 22 in and the length of the side of the base is 17 in. |
|
2 |
Step |
The given values area |
h = 22 in and l = 17 in |
3 |
Formula |
Total Surface Area of Hexagonal Prism is |
\$"Total surface area" = 6"ah" + 3\sqrt(3a^2)\$ |
4 |
Step |
Now plug the values in the formula |
\$"Total surface area" = 6 times 17 times 22 + 3 \sqrt(3 times (17)^2\$ |
5 |
Step |
After simplification |
\$"Total surface area" = 2244 + 1501.68\$ |
6 |
Step |
Make it simpler |
Total surface area = 3745.68 sq.in |
7 |
Step |
Therefore the total surface area of the hexagonal prism is 3745.68 sq.in. |
