Answer:
[tex]5820[/tex] square inches
Step-by-step explanation:
For the rectangular prism in the middle:
[tex]24*30=720*2=1140[/tex]
[tex]10*30=300*2=600[/tex]
[tex]1140+600=1740[/tex]
For the left triangular prism:
[tex]10*24=240[/tex]
[tex]26*30=780[/tex]
[tex]24*30=720[/tex]
[tex]10*30=300[/tex]
[tex]240+780+720+300=2040[/tex]
For the other right triangular prism, it's the same.
Let's add now to find the surface for the whole ramp.
[tex]1740+2040+2040=5820[/tex]
Hope this is helpful to you
