The base is an equilateral triangle each side of which has length 10. The cross sections perpendicular to a given altitude of the triangles are squares. How would you go about determining the volume of the solid described?

The textbook answer is 500/3(sqrt3)

However I got 250 could you explain how to do this problem, thanks.
