To find:
The surface area ofregular pyramid or cone. Round to the nearest whole number.
Answer to Problem 10.24EP
The surface area of our given regular pyramid is approximately 31 square mm.
Explanation of Solution
Given:
A regular pyramid:
Concept used:
Surface area of regular pyramidis area of base plus area of lateral faces.
Calculation:
We have been given that area of base is 6.9 square mm.
The area of each lateral face would be same. So we will multiply area of one lateral face by 4 to get area of four lateral face.
To find area of lateral face, we will use area of
Therefore, the surface area of our given regular pyramid is approximately 31 square mm.
