The sum of the edges of a cuboid is 64cm. It is known that the length is 8cm, the width is 5cm, the height is (3) cm, the surface area is (158) cm2, and the volume is (120) cm3. The denominator is the sum of all the simplest true fractions of 10, which is (2). There are (4) false fractions of 4. The formula is: 64 △ 4-5-8 = 3cm, the surface area = (3 × 5 + 3 × 8 + 5 × 8) ×
