The surface area of the smaller solid is found to be 214 square meters.
<h3>What is Surface area?</h3>The surface area is given as the sum of the area of all the faces of a three-dimensional object.
The same shape has equivalent ratio of the surface area to volume. It is given as:
On considering the power of 6 at both the sides of the equation:
Considering area 1 and volume 1 for the larger solid, and area 2 and volume 2 for the smaller solid, substituting the values give:
By solving the above equation, the area of the smaller solid is found as 214 square meters. Thus, option B is correct.
