Then you can plug into the equation ab = 6 to solve for b:
When the triangle is rotated about its longer leg, a becomes the height
and b becomes the base radius, so
5 . A
To find the volume of a pyramid, you need the area of the base, which is
given here as 12, and you need the height, which here you have to figure
out. Imagine a triangle that includes the height and one of the lateral
edges:
This triangle is a right triangle. The hypotenuse is the same as a side of
one of the equilateral triangles, which is the same as a side of the square,
which is the square root of 12, or
