Question

Sketch the net of a triangular prism whose
ends are right angled triangles of sides 6 cm,
8 cm and 10 cm and whose length is 12 cm.​

Answer 1

Step-by-step explanation:

Area = √( 9 x 3 x 3 x 3 )

⇒ = 9 √3 

Area = 9 x 1.73 

Area of ΔABC = 15.57 cm 2 

Lateral surface area = ph = 18 x 8 = 144 cm 2 

Total surface area = 2 x area of base + ph

⇒ = 2 x 15.57 + 144 

∴ Total surface area = 175.14 cm 2
