Formula to find the surface area of a triangular prism
AleksAgata [21]

Step-by-step explanation:

In the mensuration of a triangular prism we can find the total surface area by solving for the areas of  individual shape.

The triangular prism consist of

1. three rectangular surfaces

2. two triangular surfaces.

Hence the total surface area is the sum of the areas of the rectangular surface

= (l* w) +( l*w)+(l*w)\\

and the sum of all areas of triangular surfaces

= (\frac{1}{2}bh) + (\frac{1}{2}bh)

<u><em>In summary just find the area of each shape and add them together.</em></u>

¿Cuál es el valor de 0.1561 redondeado a la décima más cercana?
Alik [6]

Answer: 0.2

Step-by-step explanation: Necesitamos ajustar la estimación de 0.1561 al décimo más cercano.

El número después del decimal es el número en el décimo lugar. Considere el número a un lado del lugar de las décimas y utilice el número para decidir si se reunirán o seguirán siendo el equivalente. Observe que el número a un lado del décimo lugar es mayor o equivalente a 5 o menos de 5. En el caso de que ese número sea más digno de mención o equivalente a 5, en ese punto el número se reunirá aún en la remota posibilidad de que ese número es menor de 5, en ese momento el número no se reunirá. Permanecerá igual.

Consideremos el número dado 0.1561

El número en el lugar de las décimas es 1

El número después del punto de las décimas es 5 (que es más prominente o equivalente a 5)

De esta manera, el número se reunirá en 0,2
