If the ratio of the triangular pyramids' surface areas is 4: 9, what is f?

(work shown/rexplained is appreciated.) : )

The answer to your question is f = 10.35 in

Step-by-step explanation:

Data

Proportion = 4:9

height 1 = 4.6 in

height 2 = f

Process

1.- Write the proportion

2.- Solve for f

                                           4f = 41.4

                                           f = 10.35 in
