Answer :
Perimeter of cross-section = 48 cm
Length of prism = 10 cm
Lateral surface area = Perimeter of cross-section × Length of prism
= 48 cm × 10 cm
= 480 cm²
Perimeter of cross-section = 48 cm
Length of prism = 10 cm
Lateral surface area = Perimeter of cross-section × Length of prism
= 48 cm × 10 cm
= 480 cm²
