Answer:
Surface area of the cube = 216 square units
Step-by-step explanation:
Let the length of a side of a cube = x unit
Diameter of the sphere inscribed in this cube = length of a side of the cube
Volume of the sphere = ![\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
Where r = radius of the sphere =
units
36π = ![\frac{4}{3}\pi (\frac{x}{2})^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%28%5Cfrac%7Bx%7D%7B2%7D%29%5E%7B3%7D)
36π = ![\frac{4x^{3}\pi }{24}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%5E%7B3%7D%5Cpi%20%7D%7B24%7D)
36×24 = 4x³
x = ![\sqrt[3]{\frac{36\times 24}{4} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B36%5Ctimes%2024%7D%7B4%7D%20%7D)
x = 6 units
Length of a side of the cube = 6 units
Surface area of the cube = 6×(Side)²
= 6×(6)²
= 216
= 216 square units
Answer:
The answer to your question is: 19 l
Step-by-step explanation:
Data
20 quarts to liters
Process
Rule of three
1 quart ------------------ 0.946 l
20 quarts -------------- x
x = (20 x 0.946) / 1
x = 18.92 l ≈ 19 l
So subtract 55 from 35
35 - 55 = -20
then, put -20 over 55
-20/55 equals -0.36 repeating, rounded to -0.36, which equals 36%
the negative stands for decrease, so it's around 36% decrease
Probability of passing history course = 0.59
Probability of passing math course = 0.60
Probability of passing both courses = 0.49
Probability of passing at least one = 0.59 + 0.60 - 0.49 = 0.7 ##
