Since the volume of the cube is 216 cubic inches, we have e 3 = 216 e = 6. The area of each face is e 2 = 36 square inches, and since there are six faces, the total surface area is 6 × 36 = 216 square inches. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
