Area of the lateral surface of Prism(L.S.A) = 143 sq.cm
Perimeter of the base, P = 13 cm
Concept:
Lateral surface area of a prism is the product of its base perimeter and altitude
Formula used:
Lateral surface area of Prism = Perimeter of base × Altitude (L.S.A = P × h)
Calculation:
L.S.A = P × h
⇒ h = L.S.A/P = 143/13 = 11 cm
∴ Altitude of the Right Prism = 11 cm
