Answer:
125 in^2
Explanation:
Assuming that s is the length of a side in the base.
- Surface Area is the area of every shape in the figure added together.
- In this figure you have 4 triangles and one square as the base.
- For the base you would find the area of a square (the base is a square) 5 x 5 = 25
- There are four triangles that you need to find the area of which all have the same surface area.
- To get the area of a triangle first split the triangle into 2 halves making a right triangle. This will make the dimensions 2.5 for base and 10 for height.
- Do base x height of the right triangle to get the full triangles area. (2.5 x 10 = 25).
- You now know the area of one triangle which there are four of in this problem so you can do 4 x 25.
- The surface area of the triangles is 100.
- Add the area of the base (25 + 100).
- The surface area of this figure is 125 in^2
