(05.07) A square pyramid is shown. What is the surface area?
tensa zangetsu [6.8K]
The area of a pyramid is the sum of area of the base and the area of slant triangles. 
The area of the base is 1.5 × 1.5 = 2.25 cm²
The slant height of each triangle, s is 3 cm
The area of the triangles = 1/2 × 1.5 × 3 × 4
                                        = 9 cm²
Therefore, the area of the pyramid
 =9 +2.25 
= 11.25 cm²
