To draw:
A net for the given prism or cylinder. Then find the surface area. Round to the nearest whole number.
Answer to Problem 10.19EP
The surface area of our given prism is 312 square cm.
Explanation of Solution
Given:
A prism:
Calculation:
We can see that our given prism has 3 rectangular faces and 2 triangular faces.
Upon drawing the net of our given prism, we will get our required net as shown below:
The surface area of a prism is equal to sum of areas of all faces of prism.
The area of 2 triangular faces would be:
Now we will find area of rectangular faces one by one.
Let us add all the areas.
Therefore, the surface area of our given prismis 312 square cm.
