The perimeter of a triangular prism is `36 cm`. and lateral surface area is 720 sq.cm. If the base is an equilateral triangle then,
a) What is the height of the prism?
b) Find the total surface area of the prism.

Text Solution

Verified by Experts

a) Height `=720 div 36=20 ~cm`.
b) Base edge `=36 div 3=12 ~cm`
Total surface area `=2 xx sqrt3 xx 12^2/4+720` `
=72 sqrt3+720=844.56 sq . cm . `
