×base×height

Where a is the side of a square .

As shown in the figure the solid is made up of one square and four triangle .

Total area = Area of a square + 4 × Area of a triangle

Total\ area = 5\times 5 +4\times \frac{1}{2}\times 10\times 5Total area=5×5+4×

1

×10×5

Total\ area = 5\times 5 +2\times 10\times 5Total area=5×5+2×10×5

Total area = 25 + 100

Total area = 125 in²

Therefore the surface area of the solid is 125 in² .
