Answer 1

The surface area of the composite figure is; SA = 224 in.²

How to find the area of a Composite Figure?

From the composite figure attached, we can find the surface area of each of the rectangular/square external face seen as;

SA= 2(10 * 2) + 2(4 * 7) + 2(4 * 4) + 2(4 * 2) + (4 * 7) + (10 * 4) + (3 * 4)

SA = 40 + 56 + 32 + 16 + 28 + 40 + 12

SA = 224 in.²

Thus, we can conclude that the  surface area of the composite figure is;

SA = 224 in.²
