Question

find the missing side length in these similar solids.

Explanation:

Step1: Set up the proportion

Since the solids are similar, the ratios of corresponding side lengths are equal. Let the missing side length be \(x\). We have the proportion \(\frac{8}{10}=\frac{4}{x}\).

Step2: Cross - multiply

Cross - multiplying gives \(8x = 4\times10\).

Step3: Solve for \(x\)

\(8x=40\), then \(x=\frac{40}{8}=5\).

Answer:

\(5\)
