The volume of the right rectangular prism is the product of all its dimensions, length, width and height. Since all these dimensions are given, therefore, we can directly calculate the volume of the right rectangular prism by substitution to the formula.

V = L*W*H
V = (2.5 ft)(3 ft)(1.5 ft)
<em>V = 3.375 ft³ or 3 and 3/8 ft³</em>

The volume of the prism is the product of the area of the base (Ab) by the height (h). In this case, the base is a rectangle, so its area is the product of the two contiguous sides (a · b).
  Therefore, the volume of the prism will be given by:
  V = (2 1/2) * (3) * (1 1/2) = 11.25 ft ^ 3

Indica si cada afirmación es verdadero (v) o falso (f) .
Ksivusya [100]

<span>A es falso porque podría dividirse por negativo.

B es verdadero porque el divisor siempre entrará en el dividendo.

C es falso porque cambiar el orden dará lugar a respuestas diferentes.

D es falso porque la propiedad asociativa no se aplica a la división.

E es falso porque no es "solo suficiente", aún necesita asegurarse de que el dividendo sea un número entero y el divisor sea un factor del dividendo.</span>
