Answer:

Lateral surface area of the pyramid= [tex]48\,\,inch^2[/tex]

Step-by-step explanation:

The lateral surface area of the pyramid is the area of the all of its four triangular faces, excluding base :

Area of a triangle is:

      [tex]=\dfrac{1}{2} \times Base \times Height\\[/tex]

Base= 3 inches

Height=8 inches

Lateral surface area of the pyramid:  

                              [tex]=4(\dfrac{1}{2}\times Base \times Height )\\\\=4(\dfrac{1}{2} \times 3 \times 8 )\\\\=4(\dfrac{1}{2} \times 24 )\\\\=4 \times 12\\\\=48\,\,inch^2[/tex]

Lateral surface area of the pyramid= [tex]48\,\,inch^2[/tex]
