The volume of the larger cube is 3*3*3, which is 27.
The volume of the smaller cubes is 1*1*1, which is 1.
27/1=27
That means all cubes will be used, so only the placement of the cubes matter.
The center of the cube will show no sides,
The center of the face will show 1 side, which has a surface area of 1sq.in.
Since there are 6 white cubes and 6 faces with 6 face centers, and only one cube center, there will be 5 cubes on the center of the faces and 1 in the cube center.
This means there will be 0 faces of 1 cube and 1 faces shown for the rest of the cubes. Since each face is 1sq.un., the rest is math
(0*1)+((1*1)5)
(0)+(1*5)
0+5
5sq.un. of the cube is white.
a=The fraction of surface area showing
b=Surface area of large cube
b=3*3*number of sides on cube(6)
5*a=b
5*a=54
a=54/5
Your answer is 54/5.
Answer:
The median would change the most
Step-by-step explanation:
The mode will not change, because the only duplicate number is 20
The mean will change from 53.22 to 55.2 when you put 73 into the set
and the median will change from 67 to 70 when you put 73 into it
Answer: 400
Step-by-step explanation: cube root 8000 then that times itself
The airplane went 5195.33 km
Step-by-step explanation:
Distance = speed × time
The given is:
1. An airplane flies for 3.5 hours with a constant speed of 840 km/h
2. Then for another 3 hours 19 minutes with a constant speed of
680 km/h
We need the distance it traveled
For the first part
∵ The time is 3.5 hours
∵ The speed is 840 km/h
∵ Distance = speed × time
- Substitute the values of the speed and the time in the rule
∴ Distance = 840 × 3.5
∴ Distance = 2940 km
For the second part
∵ The time is 3 hours and 19 minutes
- We must change the minutes to hour
∵ 1 hour = 60 minutes
∴ 19 minutes =
hour
∴ The time is
hour
∵ The speed is 680 km/h
∴ Distance = 680 × ![3\frac{19}{60}](https://tex.z-dn.net/?f=3%5Cfrac%7B19%7D%7B60%7D)
∴ Distance =
km
∴ The total distance = 2940 + ![2255\frac{1}{3}](https://tex.z-dn.net/?f=2255%5Cfrac%7B1%7D%7B3%7D)
∴ The total distance =
km
It went 5195.33 km
