Hello!
To find the surface area of a cube you use the equation

a is a side length
Put in the values we know

Square the 9
6 * 81 = 486
The answer is
Answer:
$1.29
Step-by-step explanation:
5.16 divided by 4
Answer: 0.65
Step-by-step explanation: Because when you look at the numbers you can see how to goes down more so when you subtract 2.45 from 3.1 you get 0.65
Hope this helps :)
This would be a 20% decrease. Since your going from 70 to 56, you would have a percentage of 20 for your decreasing percentage. The difference total is -14.

Answer: approximately 0.19 meters long</h3>
The more accurate value is 0.18982439916059 but this value isn't exact

Explanation:
The volume of this rectangular block is 0.24*0.19*0.15 = 0.00684 cubic meters.
If we had a cube of this volume, then it has some side length x such that x^3 = 0.00684
Apply the cube root to both sides. This is the same as raising both sides to the 1/3 power
![x^3 = 0.00684\\\\x = \sqrt[3]{0.00684}\\\\x = (0.00684)^{1/3}\\\\x \approx 0.18982439916059\\\\x \approx 0.19\\\\](https://tex.z-dn.net/?f=x%5E3%20%3D%200.00684%5C%5C%5C%5Cx%20%3D%20%5Csqrt%5B3%5D%7B0.00684%7D%5C%5C%5C%5Cx%20%3D%20%280.00684%29%5E%7B1%2F3%7D%5C%5C%5C%5Cx%20%5Capprox%200.18982439916059%5C%5C%5C%5Cx%20%5Capprox%200.19%5C%5C%5C%5C)
The side length of the cube is approximately 0.19 meters long
