A cuboid can be cut into two cubes. After cutting, the surface area of the cuboid increases by 18 m2. The surface area of the cuboid is______ M 2, the volume is______ M 3

A cuboid can be cut into two cubes. After cutting, the surface area of the cuboid increases by 18 m2. The surface area of the cuboid is______ M 2, the volume is______ M 3

The area of the bottom of the cuboid: 18 △ 2 = 9 (square meters) the surface area of the cuboid: 9 × 10 = 90 (square meters) because 3 × 3 = 9, the length, width and height of the cuboid are 3 × 2 = 6 (meters), 3 meters and 3 meters respectively, and the volume of the cuboid: 6 × 3 × 3 = 54 (cubic meters). A: the surface area of the cuboid is 90 square meters, and the volume is 54 cubic meters
