Solution

Para encontrar el área de la superficie de un prisma rectangular, necesitamos calcular el área de cada una de sus seis caras y luego sumarlas.

Las dimensiones del prisma son:

  • Largo (l) = 1 yarda
  • Ancho (w) = 4.9 yardas
  • Altura (h) = 1 yarda

Las fórmulas para el área de las caras son:

  • Dos caras de l x w
  • Dos caras de l x h
  • Dos caras de w x h

Primero, calculamos el área de cada par de caras:

  1. Área de las dos caras de l x w: 2×(1 yarda×4.9 yardas)=2×4.9=9.8 yardas22 \times (1 \text{ yarda} \times 4.9 \text{ yardas}) = 2 \times 4.9 = 9.8 \text{ yardas}^2

  2. Área de las dos caras de l x h: 2×(1 yarda×1 yarda)=2×1=2 yardas22 \times (1 \text{ yarda} \times 1 \text{ yarda}) = 2 \times 1 = 2 \text{ yardas}^2

  3. Área de las dos caras de w x h: 2×(4.9 yardas×1 yarda)=2×4.9=9.8 yardas22 \times (4.9 \text{ yardas} \times 1 \text{ yarda}) = 2 \times 4.9 = 9.8 \text{ yardas}^2

Finalmente, sumamos todas las áreas: 9.8 yardas2+2 yardas2+9.8 yardas2=21.6 yardas2 9.8 \text{ yardas}^2 + 2 \text{ yardas}^2 + 9.8 \text{ yardas}^2 = 21.6 \text{ yardas}^2

Por lo tanto, el área de la superficie del prisma rectangular es de 21.6 yardas cuadradas.
