Answer: 976m^2
Explanation:
An easy way to find the surface area of a prism is to find the area of each side and add them all together.
Area of rectangle:
14mx10m=140m^2
Area of rectangle:
25mx10=250m^2
Since there are 2 of the long rectangles, you multiply by 2:
250m^2x2=500m^2
Area of triangle:
(24mx14m)/2=168m^2
Since there are 2 triangles, you multiply by 2:
168m^2x2=336m^2
Surface Area:
140+500+336=976m^2
