Respuesta :

The pyramid's surface area is = 409.6 cm2.

The provided pyramid's surface area is equal to its square base plus its lateral sides.

The square base's area is given by (Side)2

= (8)2

= 64 cm2.

Area of the lateral side = 1/2 (Lateral height)(Base)

= √4² + (9.2)

2 [By applying Pythagoras theorem]

82.81+36

= √100.64

= 10.8 cm

Area of the lateral side = (8)(10.8)

= 86.4 cm²

The provided pyramid's surface area is calculated as follows:

Area of the base + 4(Area of one lateral side)

= 64 + 4(86.4)

= 409.6 cm2.
