An object is made of a prism with a spherical cap on its square shaped top. The cap's base has a diameter equal to the lengths of the top. The prism's height is 12 , the cap's height is 4 , and the cap's radius is 3 . What is the object's volume?

color(blue)("Volume"=(1296+80pi)/3 " cubic units")

Explanation:

This is a square prism. The radius of the cap is 3, so the width of the square is 6.

Volume of prism:

Area of base x height.

6^2xx12=432

Volume of a spherical cap is given by:

V=(pih^2)/3(3r-h)

V=(pi(4)^2)/3(3(3)-4)

V=(16pi)/3(5)=(80pi)/3

Total volume:

432+(80pi)/3=(1296+80pi)/3 cubic units.
