Volume = (1/3)*(base area)* height

(1/3)*(2 * 2) * h = 8

h = 8*3 / (2 * 2)

h = 6 feet.

Volume a square pyramid is expressed as the one third of the product of the base area and the hight of the shape.

Volume = (1/3)*(base area)* height

Substituting the given values, we have:

(1/3)*(2 * 2) * h = 8

h = 8*3 / (2 * 2)

h = 6 ft

Therefore, the correct answer among the choices is option A.

en un colegio mixto hay x estudiantes distribuidos en c cursos. Si hay m niños por curso, ¿Cuantas niñas hay en el colegio?
Tomtit [17]

La ecuación que nos dice cuantas niñas hay en el colegio es:

A = x - c*m

¿Como encontrar una expresión para la cantidad de niñas?

Sabemos que hay un total de x estudiantes, definimos las variables:

  • A = cantidad total de niñas
  • B = cantidad total de niños.

Entonces tenemos A + B = x

Tambien sabemos que los estudiantes estan divididos en c cursos, de tal forma que hay m niños por curso.

Entonces c por m es igual a la cantidad total de niños:

c*m = B

Reemplazando esto en la ecuación de arriba podemos obtener:

A + c*m = x

A = x - c*m

Esta es la ecuación que nos da el numero total de niñas en el colegio.
