What is the surface area of a square pyramid with a height of 12 mm and a base that measures 10mm on each side?

The surface area is: 360 millimeters squared

Step-by-step explanation:

Base Surface Area =  10 squared

=  100 millimeters squared

Lateral Surface Area =  

2×10×√  

10/2 squared+ 12 squared

=  260 millimeters squared

Total Surface Area = 360 millimeters squared

Hope this helps!
