Two similar pyramids have base areas of 12.2 cm2 and 16 cm2. The surface area of the larger pyramid is 56 cm2.What is the surface area of the smaller pyramid?

For similar pyramids, the ratio of their surface areas is the same as the ratio of their base areas. The smaller pyramid’s surface area is 56 × (12.2 ÷ 16) = 42.7 cm² (to the nearest tenth). Therefore, the answer is 42.7 cm².
