When the height of a cuboid is increased by 3M, it becomes a cube. The surface area of a cuboid is increased by 48 square meters compared with that of the original cuboid What's the formula
What do you mean by volume or what? The volume of a cuboid is 16 square meters, its length and width are 4, and its height is 1
If the edge length of a cube is A-1, then the volume of a cube is A-1____ And the surface area is_______
Volume: A-1 * A-1 * A-1
Surface area: A-1 * 6
If the edge length of a cube is increased a times, its surface area and volume will be increased () times
S=6m^2,V=m^3.
S'=6(am)^2=a^2*S.
V'=(am)^3=a^3*V.
The surface area is (a ^ 2) times larger and the volume is (a ^ 3) times larger
Saw a stick into several equal sections, a total of four times, each section is a fraction of the stick
After sawing four times, I cut it into five sections, one fifth each
The 2-meter-long stick is sawed into 5 sections on average. Each section is a fraction of the length of the stick. Each section is a fraction of the length of the stick
Not a fifth
Two fifths of the length
A wooden stick, saw it into 16 parts, take 4 / 5 of one section, and ask how many parts of the total length it occupies
1/16 * 4/5=1/20
A: it accounts for 1 / 20 of the total length
Saw a 6-meter-long wooden stick into 4 sections of the same length. What is the length of each section? What is the proportion of each section?
The length of each section is 6 △ 4 = 3 / 2 meter
Each section accounts for 1 / 4 of the total length
When a stick is sawed into four sections, how much time does it take to saw off one section?
One third of a stick needs to be sawed three times to cut into four pieces
What is the value of m if the value of 4-3m-1 = 2-1m + 3 is equal?
3
3 / 8 of 1m and 1 / 8 of 3M, which is bigger
The same size, all 0.375 M
