Answer:
5520 cubic cm
Explanation:
The first step you have to complete in order to get the solution is to calculate the surface area of the two isosceles triangles. The formula for calculating a triangle is (hxb)/2. This makes the equation (40x18)/2, which equals 360. Because we have two of them, we multiply the answer by 2, which means the surface area of the two triangles totals 720. Next, we calculate the two big rectangles in the shape. The formula for calculating a rectangle is hxw which, in this case, makes 41x48. This equals 1968, and because we have two of them, this equals 3936. Next, we have to calculate the smaller rectangle, which is 18 by 48 feet which equals 864. Finally, we have to add these totals together, which creates the equation 720+3936+864, which equals 5520.
