The surface area of the given figure is 288 km²
<h3>Calculating surface area </h3>
From the question, we are to determine the surface area of the figure
The given figure is a square-base pyramid
Surface area of the pyramid = (10×10) + 4× 1/2(10×9.4)
Surface area of the pyramid = (100) + 2(94)
Surface area of the pyramid = 100 + 188
Surface area of the pyramid = 288 km²
Hence, the surface area of the given figure is 288 km²
