Answer:

5820 square inches

Step-by-step explanation:

For the rectangular prism in the middle:

24*30=720*2=1140

10*30=300*2=600

1140+600=1740

For the left triangular prism:

10*24=240

26*30=780

24*30=720

10*30=300

240+780+720+300=2040

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

1740+2040+2040=5820

Hope this is helpful to you
