The edge length of a cube increases by a times, the total edge length increases by () times, the surface area increases by () times, and the volume increases by () times?


The edge length of a cube increases by a times, the total edge length increases by (a) times, the surface area increases by (A's Square) times, and the volume increases by (A's Cube) times?



The edge length of a cube is a centimeter, its volume is (), the surface area is (), the bottom area is (), and the total edge length is ()?


The volume is a ^ 3 (the third power of a)
The surface area is 6A ^ 2
The bottom area is a ^ 2
The total edge length is 12a



The edge length of the cube is three times larger, and the volume of the cube is () times larger
A. 3B. 6C. 9D. 27


According to the volume calculation method of cube and the change law of factor and product, if the edge length of a cube is increased by 3 times, its volume will be increased by 27 times



For a piece of iron wire, half of it is less than 1 meter in the first time, the remaining half is more than 1 meter in the second time, and 2.5 meters are left in the end. The original length of the iron wire is long______ Rice


[(2.5 + 1) × 2-1] × 2, = [3.5 × 2-1] × 2, = [7-1] × 2, = 6 × 2, = 12 (m); answer: the original length of wire is 12 M



Cut the 12 meter long rope into 10 sections on average, and each section is full length______ , length of each segment______ Rice


The length of each segment is 12 × 110 = 120



The 3-meter-long rope is cut into 5 sections on average. How many parts of the total length is each section? How many meters is each section long?


One fifth of the total length of each section, 3 / 5m = 0.6m



1. Divide the 3 / 4 meter long rope into 5 sections on average. How much of the total length is each section? How long is each section?
2. Xiaofang walks four kilometers in two-thirds of an hour, and it takes () hours to walk one kilometer per hour. 3. Boys are one fifth more than girls


1. Divide the rope 3 / 4 meters long into 5 sections, each section accounts for 1 / 5 of the total length, and each section is 20 / 3 meters long
1÷5=1/5
3/4x1/5=3/20m
2. Xiaofang walks 4 kilometers in two-thirds of an hour, 6 kilometers per hour, 1 kilometer takes 1 / 6 hour
3. The number of male students is one fifth more than that of female students, and the quantitative relationship (the number of male students more than that of female students = the number of female students X1 / 5)
After a part is removed, there is still a quarter left. The quantity relation is (the rest = total number x 1 / 4)



The 4-meter-long rope is divided into 5 sections, each of which accounts for a few percent of the total length, and the length of each section is several meters


1/5 (1/5)*4=4/5m



Divide a 2-meter-long wire into 5 sections. How many parts of the wire is each section? How many meters is each section?


Each segment accounts for 1 / 5, and the segment is 0.4m



A wire is divided into three sections. The first section is 5 meters long, the second section is 6 meters long, and the third section is 7 meters long. What percentage of the total length of the wire does each section account for?


The first paragraph accounts for:
5÷(5+6+7)=5/18
The second paragraph accounts for:
6÷(5+6+7)=6/18=1/3
The third paragraph accounts for:
7÷(5+6+7)=7/18
