Question

Find the total surface area of this triangular prism.

25 cm
24 cm
10 cm
14 cm

Answer 1

Explanation:

`\boxed{\text{Area of triangular prism = length*(a+b+c) + 2*base area}}`

Here a, b,c are the sides of the triangle.

a = 14 cm ; b = c = 25 cm and length = 10 cm

`\boxed{\text{Base area=2*$(1)/(2)*base*height$=base *height}}`

base = a = 14 cm & h = 24 cm

Base area = 14*24

= 336 cm²

Total surface area = 10*(14+25+25) + 336

= 10*64 + 336

= 640 + 336

= 976 cm²
