Answer:
100 m²
Step-by-step explanation:
The two solids seem to have volumes of side³
Since the larger solid is the cubed root of 9 and the smaller solid is the cubed root of 5.
The surface are of the larger solid is the square root of 18, which is also 9 × 9 × 4 which translates to side² × 4
Using this information we can apply this formula to find the surface area of the smaller solid: side² × 4 = (5)² × 4 = 100 m²
