Step-by-step explanation:
To find the surface area, we need to add the area of each face on the square pyramid.
We can look at a net of the shape to find the area of each face.
Let's start by finding the area of the square base.
=4×4
=16
Next, let's find the area of each of the triangular faces.
Area of a triangle
=
2
1
⋅base⋅height
=
2
1
⋅4⋅5
=
2
1
⋅20
=10
Four of the faces are triangles. Each triangle has the same base and height. The total area of these four triangles is \blueD{10}+\blueD{10}+\blueD{10}+\blueD{10}10+10+10+10start color #11accd, 10, end color #11accd, plus, start color #11accd, 10, end color #11accd, plus, start color #11accd, 10, end color #11accd, plus, start color #11accd, 10, end color #11accd
Hint #55 / 5
Finally, we add the area of all 555 faces. The surface area of the rectangular prism can be found with the following expression:
