The surface area of the cuboid model is {] square centimeter and the volume is cubic centimeter

The surface area of the cuboid model is {] square centimeter and the volume is cubic centimeter


Length of cuboid: 3 × 3 = 9 cm
Surface area: 2 × (3 × 3 + 3 × 9 + 9 × 3) = 126 square centimeters
Volume: 3 × 3 × 9 = 81 CC



Four small cubes with a volume of 1cm3 are used to form a cuboid with the smallest surface area of 2______ .


(1) 4 × 1 arrangement: length, width and height are 4cm, 1cm and 1cm respectively, and the minimum surface area is (4 × 1 + 4 × 1 + 1 × 1) × 2 = 9 × 2 = 18 (cm2); 2 × 2 arrangement: length, width and height are 2cm, 2cm and 1cm respectively, and the minimum surface area is (2 × 2 + 2 × 1 + 2 × 1) × 2 = 8 × 2 = 1



Using four cube blocks of the same size to make a cuboid, the surface area is reduced by 32 square centimeters. How many cubic centimeters is the volume of each small regular?
