Introduction

When dealing with similar solids, understanding the relationship between their surface areas and corresponding side lengths is crucial. In this article, we will delve into the concept of similar solids, explore the given ratio of surface areas, and derive the ratio of their corresponding side lengths.

What are Similar Solids?

Similar solids are three-dimensional shapes that have the same shape but not necessarily the same size. They can be thought of as scaled-up or scaled-down versions of each other. The key characteristic of similar solids is that their corresponding sides are proportional.

The Ratio of Surface Areas

The given ratio of surface areas is $16: 144$. This ratio can be expressed as a fraction, $\frac{16}{144}$, which simplifies to $\frac{1}{9}$. This means that the surface area of the smaller solid is $\frac{1}{9}$ that of the larger solid.

The Relationship Between Surface Area and Side Length

The surface area of a solid is directly proportional to the square of its side length. Mathematically, this can be expressed as:

Surface Area ∝ (Side Length)^2

This relationship can be used to derive the ratio of corresponding side lengths from the given ratio of surface areas.

Deriving the Ratio of Corresponding Side Lengths

Let's assume that the side length of the smaller solid is $x$ and the side length of the larger solid is $y$. Using the relationship between surface area and side length, we can set up the following equation:

$\frac{16}{144} = \frac{x^2}{y^2}$

Simplifying the equation, we get:

$\frac{1}{9} = \frac{x^2}{y^2}$

Taking the square root of both sides, we get:

$\frac{x}{y} = \frac{1}{3}$

This means that the ratio of the corresponding side lengths is $1: 3$.

But Wait, There's More!

However, we are not done yet. We need to consider the fact that the ratio of surface areas is given as $16: 144$, which can also be expressed as $4: 36$. This means that the ratio of corresponding side lengths can also be expressed as $4: 6$.

Conclusion

In conclusion, the ratio of corresponding side lengths of two similar solids with a surface area ratio of $16: 144$ is $4: 6$. This can also be expressed as $1: 3$ or $\frac{4}{6}$. The correct answer is:
