Answer:
Therefore,
The surface area is
[tex]\textrm{Total Surface Area of Prism}=252\ units^{2}[/tex]
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,
[tex]\textrm{Total Surface Area of Prism}=bh + (s_{1}+s_{2}+s_{3})W[/tex]
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
[tex]\textrm{Total Surface Area of Prism}=9\times 7 + (9 + 9 + 9)\times 7=252\ units^{2}[/tex]
Therefore,
The surface area is
[tex]\textrm{Total Surface Area of Prism}=252\ units^{2}[/tex]
