To find the surface area of the figure, we need to calculate the area of each side of the figure and then add them all together.
The figure consists of a rectangular prism with dimensions 5ft, 7ft, and 6ft.
The surface area of a rectangular prism can be found by adding the areas of the six faces.
The area of a rectangle is given by the formula: length × width.
The area of the top and bottom faces (5ft × 6ft) is 30ft² each.
The area of the two side faces (7ft × 6ft) is 42ft² each.
The area of the front and back faces (5ft × 7ft) is 35ft² each.
Therefore, the surface area of the figure is 30ft² + 30ft² + 42ft² + 42ft² + 35ft² + 35ft².
Simplifying, we get 144ft² + 77ft² + 70ft².
Adding these together, we find that the surface area of the figure is 291ft².
