What is the surface area of this square pyramid. 

 

My answer was 72 ft², but I felt like I might be wrong. If someone could double-check. Thank you

Area of the base  =  36

 

Area of sides

We have 4 equal triangles.....each  has a base of 6  and a height of 3....so the area of the sides  =

 

4 * (1/2) (6) (3)   =    2 * 6 * 3    =  36

 

 

So....the toal area  is  [ 36 + 36 ]  =    72  ft^2 

 

You are correct  Agent    !!!!!
