The volumes of two similar solids are 210 m cubed and 1 comma 680 m cubed The surface area of the larger solid is 856 m squared What is the surface area of the smaller solid?

The smaller-to-larger volume ratio is 210 ÷ 1,680 = 1/8. For similar solids, the linear scale factor is the cube root of the volume ratio, so it is 1/2; surface areas scale by the square of that factor, or 1/4. Thus, the smaller surface area is 856 × 1/4 = 214 m², which is choice A.
