(1) There is a square with a total edge length of 48 cm. Its surface area is () square cm and its volume is () square cm (2) There is a cuboid that intersects at a vertex and three edges are 5 decimeters, 4 decimeters and 3 decimeters long respectively. The total edge length of the cuboid is () decimeters, the surface area is () square decimeters, and the volume is () cubic decimeters

The cube has 12 ridges, and each ridge is equal
48 / 12 = 4cm
Surface area = 4 ^ 2 * 6 = 96 square centimeter volume = 4 ^ 3 = 64 cubic centimeter
two
The total edge length of cuboid = (5 + 4 + 3) * 4 = 48 decimeters
Surface area = 2 * (5 * 4) + 2 * (5 * 3) + 2 * (4 * 3) = 94 square decimeters
Volume = 5 * 4 * 3 = 60 cubic decimeter
