Answer:

The value of k is;

[tex]k=\frac{27}{8}[/tex]

Explanation:

Given the two similar Pyramids with surface area;

[tex]\begin{gathered} A=29.16in^2 \\ B=2.56in^2 \end{gathered}[/tex]

The scale factor is the ratio of their corresponding lengths. which will also be equal to the square root of the ratio of their corresponding Surface Area.

[tex]k=\frac{\text{Length dimension of Pyramid A}}{\text{Length dimension of Pyramid B}}=\sqrt[]{\frac{\text{Surface area of Pyramid A}}{\text{Surface area of Pyramid B}}}[/tex]

Substituting the given surface areas;

[tex]\begin{gathered} k=\sqrt[]{\frac{29.16}{2.56}} \\ k=\sqrt[]{\frac{729}{64}} \\ k=\frac{27}{8} \end{gathered}[/tex]

Therefore, the value of k is;

[tex]k=\frac{27}{8}[/tex]
