解题步骤

1. Understand the question

   22 a display case is made of one rectangular prism stacked on top of a rectangular prism. (not drawn to scale) what is the volume, in cubic feet, of the display case?

2. Explanation

   Step1: Calcular volumen del prisma inferior

   El volumen de un prisma rectangular se calcula como $V = l \times w \times h$. Para el prisma inferior: $l=5$ ft, $w=4$ ft, $h=3$ ft.
   $V_1 = 5 \times 4 \times 3 = 60$ ft³

   Step2: Calcular volumen del prisma superior

   Para el prisma superior: $l=4$ ft, $w=3$ ft, $h=2$ ft.
   $V_2 = 4 \times 3 \times 2 = 24$ ft³

   Step3: Sumar los dos volúmenes

   El volumen total es la suma de los volúmenes de los dos prismas.
   $V_{total} = V_1 + V_2 = 60 + 24$

3. Final answer

   84 cubic feet
