Explanation:
First, let's find the area of the rectangular sides using the dimensions given.
16 x 7 = 112
112 is just for one rectangle. We need to find the area for 3 rectangles.
112 x 3 = 336
Now, we need to find the area of the triangle. Using the formula let's find the area.
bh/2
7 x 8/2
56
Our answer is 56 as we find the area of two triangles and 28 x 2 equals 56. To find the prism's total area, we have to add the areas altogether.
56 + 336 =
Answer: 392
