Answer:
Answer: 216 cm2 (square centimetres , in your question you had to put cm3, cubic centimetres, it's IMPORTANT )
Step-by-step explanation:
A perfect cube by definition has 3 equal dimensions, as an immediate rule: volume and total surface are equal, only the unit of measure changes (cubic for the volume, square for surface).
But let's calculate it anyway:
Volume = Edge * Edge * Edge = length * width * depth = (remember: all edges are equal in this case)
so Edge =
in your example Edge = = 6cm
So the surface of one side is 6*6 = 36
There are 6 sides in total, so the total surface is 6*36 = 216
Note: I call them "edges" but in case of a cube most say just "length"
The answer is 4 hope this helps
Correct answer is A. For example 50/2= 25 which is odd
If so then the equation will move 4 units to the right. True.
1. 4.5g + 6 < = 40
4.5g < = 40 - 6
4.5g < = 34
g < = 34/4.5
g < = 7.56
True statement : John can buy 7 gallons but not 8
2. 250 + 3b < = 800
3b < = 800 - 250
3b < = 550
b < = 550/3
b < = 183.33
True statement : The maximum number of new baseballs that can be purchased is 183
3. 3x + 6 > 15
3x > 15 - 6
3x > 9
x > 9/3
x > 3
4. 4x - 6 < 2x + 8
4x - 2x < 8 + 6
2x < 14
x < 14/2
x < 7
5. 3 - 2x > 9
-2x > 9 - 3
-2x > 6 ...when dividing by a negative, u flip the inequality sign
x < -6/2
x < -3
True statement : - 2
7. 3x - 3 < -12 OR -4x < = -32
3x < -12 + 3 x > = -32/-4
3x < - 9 x > = 8
x < -9/3
x < -3
answer : x < - 3 OR x > = 8
8. -7x + 9 < 72 AND 5x - 3 < = 7
-7x < 72 - 9 5x < = 7 + 3
-7x < 63 5x < = 10
x > -63/7 x < = 10/5
x > - 9 x < = 2
answer : -9 < x < = 2
