How many times is the length, surface area and volume of a cube?

The edge length, surface area and volume of a cube increase by 2, 4 and 8 times respectively

The edge length, surface area and volume of the cube increase by 2 times, several times and several times respectively

Increase the surface area by a factor of 2 (i.e. 2 * 2 = 4)
For example:
The edge length is 2 cm and the surface area is 24 square cm. The expanded edge length is 4 cm and the surface area is 96 square cm. 96 / 24 = 4 times
Cubic expansion (2 * 2 * 2 = 8)
For example:
The edge length is 2 cm and the volume is 8 cubic cm. The expanded edge length is 4 cm and the volume is 96 cubic cm. 96 / 8 = 8 times

The edge length of the cube increases a times, the surface area and volume increase several times respectively
The length, surface area and volume of the cube increased a-fold and ()

The edge length and surface area of the cube were a-fold and A-Square respectively,
Volume expansion (a cubic)

Cut an 8-meter-long steel pipe into 5 sections on average. How long is each section? How many parts of the total length is each section
Such as the title

Each section is 1.6m long
Each section accounts for one fifth of the total length

A steel pipe is 5 meters long and divided into 8 sections on average. How many meters is each section long?

5/8

Cut a 3-meter-long steel pipe into 5 equal sections. Each section accounts for several parts of the total length, and each section is several meters long

Each section accounts for 1 / 5 of the total length, and each section is 3 / 5 of the length

There are ten steps in front of the gate of Huangqiao Grand Theater. Each step is 6 meters long, 0.9 meters wide and 0.2 meters high
(1) What is the total area of 10 steps?
(2) How many square meters is it necessary to pave these steps with floor tiles?

(1) 6 * (0.9 * 10) = 54 (M2)
(2) 6 * (0.2 * 10) + 54 = 66 (M2)

(1) The total floor area of 10 steps = length * width = 6 * (0.9 * 10) = 54 M2
2) To pave these steps with floor tiles, at least the floor area + 9 steps vertical area = 54 + 9 * (6 * 0.2) = 54 + 10.8 = 64.8 m2

There are 10 steps in front of the door of Nanjing Grand Theater. Each step is 6 meters long, 0.8 meters wide and 0.2 meters high. How many square meters is it necessary to lay the red carpet on these steps?

0.2x6x10+0.8x6x10=60

There are 10 steps in front of the door of Nanjing Grand Theater, each of which is 6 meters long, 0.8 meters wide and 0.2 meters high. How many square meters is it necessary to lay red carpet on these steps?

It is to find the sum of the areas of ten frontal planes (length multiplied by height) and ten top planes (length multiplied by width)
10*（6*0.2+6*0.8）=60
