A triangular prism has a base of 9 and height of 7. The length of each side of the triangular prism is 9 and the width of the entire prism is 7. What is the surface area?

Therefore,

The surface area is

Step-by-step explanation:

Shape is triangular prism,

Base = b = 9

Height = h = 7

The length of each side of the triangular prism ,

s₁ = s₂ = s₃ = 9

Width of the entire prism

Width = W = 7

To Find:

The surface area = ?

Solution:

Total Surface Area of Prism is given by,

Where,

b = Base

h = Height

s₁ , s₂ , and s₃ = length of each side of the triangular prism

W = width of the prism

Substituting the values we get

Therefore,

The surface area is

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
