Step-by-step explanation:
The volume of a cube is

where a is the side length,
Note: If you want to remember this formula, know that a cube is basically a bunch of squares stacked on one another vertically and horizontally
The area of a square with side length a, is

If we multiply that by the height of the cube, which is a.

That is the easy way to derive the formula of the volume of a cube.
Back on track, we know the volume so we must solve for a.
1.

Assuming you took algebra, to isolate the variable a, we must undo it being raised to the third power.
To do this, we take the cube root of both sides
![\sqrt[3]{125} = \sqrt[3]{a {}^{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125%7D%20%20%3D%20%20%5Csqrt%5B3%5D%7Ba%20%7B%7D%5E%7B3%7D%20%7D%20)
The cube root of 125 is 5 so

Answer:
First answer.
Step-by-step explanation:
We know that a complete rotation would be 360°. If the figure is being rotated 90°, this is a quarter of a complete rotation.
When looking at the given answers, only the first answer seems logical.
Answer:
$6390 se destinaron a los fondos de reserva, $7668 se destinaron a los fondos de provisión y $8520 se destinaron a los fondos de operaciones.
Step-by-step explanation:
Dado que una cooperativa de agricultores obtuvo en el año 2020 una utilidad de $42,600, de cuya suma destino el 15% para fondos de reserva, 18% para fondos de provisión y el 20% para fondos de operaciones, para calcular cada una de la sumas se debe realizar el siguiente cálculo:
100 = 42,600
15 = X
42600 x 15 / 100 = 6390
100 = 42,600
18 = X
42600 x 18 / 100 = 7668
100 = 42,600
20 = X
42600 x 20 / 100 = 8520
Por lo tanto, $6390 se destinaron a los fondos de reserva, $7668 se destinaron a los fondos de provisión y $8520 se destinaron a los fondos de operaciones.
