Given:
Volume of cuboid container = 2 litres
The container has a square base.
Its height is double the length of each edge on its base.
To find:
The height of the container.
Solution:
We know that,
1 litre = 1000 cubic cm
2 litre = 2000 cubic cm
Let x be the length of each edge on its base. Then the height of the container is:

The volume of a cuboid is:

Where, l is length, w is width and h is height.
Putting
, we get


Divide both sides by 2.

Taking cube root on both sides.
![\sqrt[3]{1000}=x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B1000%7D%3Dx)

Now, the height of the container is:



Therefore, the height of the container is 20 cm.
Answer:
66
Step-by-step explanation:
the sum of all exteriors should be 360. so add all of them up and you get 294. then you subtract it from 360 and you are left with the only missing exterior angle, 66.
Answer:

Step-by-step explanation:
A geometric mean is just
, where n is the number of terms.
i.e. Geometric mean of 5, 6, 7: there are three values, so the mean is ![\sqrt[3]{5*6*7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%2A6%2A7%7D)
Answer:
B. 2r-9
