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

Help find the volume of this equation

Liula [17]

Always know the formula for volume prism because that shape is a prism.

Formula For PRISM: BH/2 x Height.

So then we are going to solve the triangle first... 7 x 22= 154/2= 77

Then multiply by the height which is 25.

77 x 25= 1,925.

So your answer should be 1,925 meters cubed. *Don't forget to write the measurement

*hope this helps
