A
A figure formed by four or more polygons that intersect only at their edges. Prisms and pyramids are polyhedrons, but cylinders and cones are not.
2
Q
What is the formula for the Diagonal of a Right Rectangular Prism?
A
d=sqrt(l^2+w^2+h^2).
3
Q
What is an Ordered Triple?
A
A three-dimensional coordinate system that has 3 perpendicular axes: the x-axis, the y-axis, and the z-axis; written as (x,y,z).

Q
What is the formula for Distance in Three-Dimensions?
A
d=sqrt(((x2-x1)^2)+((y2-y1)^2)+((z2-z1)^2))
5
Q
What is the formula for Midpoint in Three-Dimensions?
A
M(((x2+x1)/2),((y2+y1)/2),((z2+z1)/2))
