How many cm more are the sum of the surface areas of the three cubes? 2. For a project, team a and team B work together for 10 days. Now team a works for 10 days and team B works for 6 days, leaving 1 / 6 of the whole project unfinished. How many days does it take team B to complete the whole project alone? 3. A batch of parts, if the master and apprentice cooperate, will be completed in 18 hours. Now it takes 12 hours for the master to make the parts, and then it takes 10 hours for the master and apprentice to cooperate. If the master and apprentice make the parts by themselves, how many hours will it take? (write it down arithmetically)
1. According to the meaning of the title, the surface area of the three cubes is 4 * (2cm * 2cm) = 16 (square centimeter) more than that of the assembled cuboid
If the total length of the edges of a cuboid is 60cm, the length is 5cm, and the width is 2cm, how many cm is the height?
Sum of length, width and height: 60 / 4 = 15cm
Height: 15-5-2 = 10-2 = 8cm
A: the height is 8cm
The total edge length of a cuboid is 60cm, the length is 8cm, the width is 5cm, and the height is () cm
H = 60 △ 4-8-5 = 2 cm
The length of a cuboid is 5cm, the width is 4cm, the height is 3cm, the total length of edges is () cm, its volume is () cm3, and its surface area is () cm2
Sum of edge length: 5X4 + 4x4 + 3x4 = 48 volume: 5x4x3 = 60 surface area: 5x4x2 + 5x3x2 + 4x3x2 = 94
