Respuesta :

The TSA of square basd pyramid is ,

Base area+1/2 * perimeter of base *slant height.

The slant height= 4 cm.

The side of a square=6 cm.

Perimeter of square =4*6

=24 cm.

Area of base= (6)²=36 cm²

Therefore, total surface area of pyramid is determined as,

[tex]\text{TSA}=36+\frac{1}{2}\times24\times4[/tex][tex]\text{TSA}=36+48[/tex][tex]\text{TSA}=84cm^2[/tex]

Thus the total surface area of pyramid is determined as, 84 sqcm.
