    Hello, Flower90!

    You have a cube whose sides measure 1 cm and you section it
    with a plane which passes in the vertexs A, B,C (see attachment).
    Find the volume of the pyramid formed by sectioning the cube.

    The pyramid has 4 faces: 3 isosceles right triangles and 1 equilateral triangle.

    Set the pyramid on a table with one the right triangles on the bottom.

    The volume of a pyramid is: .V .= .(1/3) (area of base) (height)

    . . The base is a right triangle with sides 1 and 1; its area is: .(1)(1) = 1/2

    . . The height of the pyramid is 1.

    Therefore, the volume is: .V .= .(1/3)(1/2)(1) .= .1/6
