Answer:
184 cm^2
Explanation:
To find the surface area, find the area of each of the faces and add them up.
Let's start with the base/bottom.
The dimensions are 6 and 10, and it is a rectangle.
Area = 6 x 10 = 60 cm^2
Next, lets do the slanted sides.
The dimensions are 10 and 5, and they are both rectangles.
Area = 10 x 5 = 50 cm^2
Since there are 2 of the slanted sides, multiply 50 by 2.
50 x 2 = 100 cm^2
Then, do the triangles.
The dimensions are 6 (base) and 4 (height)
Area = 6 x 4 / 2
Area = 24 / 2
Since there are 2 triangles, we do not need to divide by 2. We will need to multiply by 2 afterwards, so there's no point in dividing by 2.
24 cm^2
Finally, add up all the areas.
60 + 100 + 24 = 184 cm^2
Heh, funny, there's no answer choice for that... maybe ask your teacher?
