Answer:
No, she cannot fit it into the box
Step-by-step explanation:
The way to know is this is simply find the total surface area of the cube. This helps to know the capacity of the cube.
From the question, the side length of the cube is 9 inches;
Mathematically, the area of a cube is 6l^2
Thus, the total surface area of the cube = 6 * 9 * 9 = 486 square inches
Seeing that what she is trying to fix is less than the total surface area, then we can say that she cannot fix 1,000 square-inch cubes inside the box
Answer:
The answer is 1526.04
Step-by-step explanation:
First you do the formula and that is V= 3.14r^2h
V equals volume
r equals radius to the 2nd power and h equals hight 3.14 equals pie
So fill in the blanks
V=3.14 (9)^2(6)
V=3.14 (81) (6)
So 81 times 6 equals 486 then times 486 and 3.14 and that gets you 1526.04 and there is your answer

Answer: 14/45
Step-by-step explanation:
Assuming that there is no replacements:
The probability of both pens being red will be represented by P(r), and P(b) and P(g) will represents both being blue and green respectively
P(r) = 5/10 x 4/9 = 2/9
P(b) = 3/10 x 2/9 = 1/15
P(g) = 2/10 x 1/9 = 1/45
Now take all 3 probabilities and add them all together to find the probability that any 2 pen will be the same color
P = P(r) + P(b) + P(g)
P = 2/9 + 1/15 + 1/14
P = 14/45
