Question

Hii, so this was one of the questions on a previous CSAT exam (korean sat). I was curious and decided to look at a few questions. This question I found was particularly interesting and I am close to figuring it out but i keep getting stuck. Would anyone like to explain how this works and how to solve it?

Answer 1

Explanation:

Well you can calculate the area of the base side by the integration of cos - sin x over the limits x = 0 and x = π/6.

Then I think one side of the square would be cos π/6 - sin π/6.

So I think the required volume can be worked out as area of base * length of a side of the square.

I think that,s the way to do it, if i have interpreted the question correctly.
