The surface area of the given figure is 222 square units

The given figure is a triangular base pyramid with 3 rectangles and 1 triangle.

Area pf the rectangles = 3(area of rectangles)

Area of rectangle = 3(5 * 14)

Area of rectangle = 210

For the triangle

Area = 1/2 * base * height

Area = 1/2 * 8 * 3

Area = 12 units square

Surface area = 210 + 12

Surface area = 222 square units

Hence the surface area of the given figure is 222 square units
