The surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm
<h3>How to find the surface area of a figure?</h3>
The surface area of a square pyramid is equal to the sum of the ara of the base square and the four triangle.
<h3>Find the area of the square base</h3>
Area of the base = 10cm * 10cm
Base area = 100 sq,cm
Find the area of a triangle
Area of triangle = 0.5 * 10 * 14
Area of a triangle = 70 square cm
Area of 4 triangles = 4(70) = 280 sq.cm
<h3>Determine the surface area</h3>
SA = 100 + 280
SA = 380 sq. cm
Hence the surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm

Answer:
y=2
Step-by-step explanation:
Answer:
23y-8
Step-by-step explanation:
First add together all of the terms that are next to a variable:
2y+10y+5y+6y=23y
Then add together all of the integers that are alone:
-9+10+(-7)+(-2)= -8
Add the two terms together and you get:
23y-8
