Answer:
Step-by-step explanation:
The lateral area of a prism is defined as the sum of all sides in the base, multiplied by its height, that is
[tex]LA=P\times h[/tex]
Where [tex]P[/tex] is the perimeter of the base and [tex]h[/tex] is the height.
So, in this case, we have
[tex]P=3+3+3=9in[/tex]
And,
[tex]h=6in[/tex]
Replacing these values, the lateral are would be
[tex]LA=P\times h\\LA=9in \times 6in=54in^{2}[/tex]
