Answer: 72 in.2
Explanation:
Surface area is just finding the area of each shape that makes up the pyramid and add it all up like this:
Area of square base is:
4 • 4 = 16 in.2
Area of one triangle:
1/2 • 4 • 7 = 14
Multiply 14 by 4 because we have 4 triangles:
14 • 4 = 56
Add up 56 + 16 = 72
Add unit of measurement: 72 in.2
Trust ms, this is right
A brainliest would be nice if im correct!
