The surface areas of two similar pyramids are 48 m2 and 108 m2 Find the scale factor.

miskamm [114]

Answer:

$\boxed{ \text{B. }\frac{2}{ 3}}$

Step-by-step explanation:

The scale factor (C) is the ratio of corresponding sides of the two pyramids.

The ratio of the areas is the square of the scale factor.

$\frac{A_{1}}{ A_{2}} =C^{2}\\ \\\frac{48 }{108} = C^{2}\\\\ \frac{4}{9} = C^{2}\\\\ C = \frac{2}{3}\\\\$

The scale factor is $\boxed {\frac{2}{3}}$ .
