Answer:
294N
Step-by-step explanation:
La presion que ejerce sobre el suelo seria la fuerza de la caja contra el suelo. Esto se calcula multiplicando el peso de la caja por el valor de la gravedad de nuestra tierra. En esta situacion no se necesitaria las dimensiones de la caja.
Fuerza = 30kg * 9.8
Fuerza = 294N
Fuerza tiene un simbolo de N que significa Newtons que serian calculados como kg * m/s^{2} ... entonces la caja ejerce una fuerza de 294N sobre el suelo.
What would you need to know to find an unknown length?
For this case you need to know three measurements.
Two measures of the triangle that is similar and a measure of the original triangle.
Thus, the fourth measure is what will be the unknown side and is the one that we must find.
How would you find that unknown length?
Let:
a, b, c: known sides
x: unknown side
By similarity of triangles we have:
x / a = b / c
From here, we clear the value of the unknown side
