To solve this problem, we can use the properties of similar solids. When two solids are similar, the ratio of their volumes is the cube of the ratio of their corresponding linear dimensions, and the ratio of their surface areas is the square of the ratio of their corresponding linear dimensions.

Given:

• Volume of the larger solid: $V_1 = 81 \, \text{cm}^3$
• Volume of the smaller solid: $V_2 = 24 \, \text{cm}^3$
• Surface area of the smaller solid: $A_2 = 44 \, \text{cm}^2$

Step 1: Calculate the ratio of the volumes.

The ratio of the volumes of the two solids is: $\text{Volume ratio} = \frac{V_1}{V_2} = \frac{81}{24} = \frac{27}{8} = \left(\frac{3}{2}\right)^3$

Step 2: Determine the ratio of the linear dimensions.

The linear dimension ratio is the cube root of the volume ratio: $\text{Linear dimension ratio} = \frac{L_1}{L_2} = \sqrt[3]{\frac{27}{8}} = \frac{3}{2}$

Step 3: Calculate the surface area ratio.

The surface area ratio is the square of the linear dimension ratio: $\text{Surface area ratio} = \left(\frac{L_1}{L_2}\right)^2 = \left(\frac{3}{2}\right)^2 = \frac{9}{4}$

Step 4: Calculate the surface area of the larger solid.

Let $A_1$ be the surface area of the larger solid. Using the surface area ratio: $\frac{A_1}{A_2} = \frac{9}{4}$ $A_1 = A_2 \times \frac{9}{4} = 44 \times \frac{9}{4} = 44 \times 2.25 = 99 \, \text{cm}^2$

Thus, the surface area of the larger solid is 99 cm².
