Answer:
144 [tex]cm^{2}[/tex]
Step-by-step explanation:
All you need to do is find the area of all the shapes and then add them together
Front triangle:
A = b * h ÷ 2
A = 8 * 6 ÷ 2
A = 48 ÷ 2
A = 24
The front and back triangle area will be the same so the back triangle will also be 24.
Top rectangle:
A = b * h
A = 10 * 4
A = 40
Back rectangle:
A = b * h
A = 6 * 4
A = 24
Bottom Rectangle:
A = b * h
A = 8 * 4
A = 32
Now that we have all the areas for the shape, all we need to do is add them all up to find the surface area for the whole shape.
24 + 24 + 40 + 24 + 32 = 144
Hope this helped!
