Down: 1) A line segment where two faces of a solid meet2) The intersection of a solid and a plane; the shape you get when you “cut” a solid by a plane3) The continuous curved or flat area formed by all lateral faces of a solid (excluding the bases)4) A solid with a circular base and a curved lateral surface that tapers to a point called the apex. 7) A cross section produced by a plane that is parallel to one of the bases of the solid.13) A face chosen as a reference for measuring height; in prisms and cylinders there are two congruent parallel bases, while pyramids and cones have a single base.15) A corner point where edges meet on a polyhedron16) A mathematical rule expressed with symbols and variables that shows how to compute a value.21) Units used to measure volume22) A two‑dimensional pattern that can be folded along edges to form a three‑dimensional solid.23) Half of a sphere produced by cutting a sphere along a great circle.26) Any flat surface that forms part of the boundary of a polyhedron Across: 5) A solid with a single polygonal base and triangular lateral faces that meet at a common point called the apex. The height is the perpendicular distance from the apex to the plane of the base. 6) The topmost vertex where all lateral faces meet in a pyramid or cone (the single point not in the base).8) A solid with two congruent, parallel circular bases connected by a curved lateral surface. 9) A corner point where edges meet on a polyhedron10) The total area of all the outer faces of a solid.11) An informal term for a cross section produced by cutting a solid with a plane; often used when visualizing or physically cutting models12) Labels that indicate the quantity measured14) The measure of the amount of three‑dimensional space occupied by a solid. 17) The maximum amount of fluid (liquid or gas) a container can hold, measured in units of volume 18) A three‑dimensional figure that has length, width, and height (or depth) and occupies space19) A solid with two congruent, parallel polygonal bases connected by rectangular lateral faces. The cross section parallel to the bases is the same shape as the bases. 20) A circle on a sphere whose center coincides with the sphere’s center; it has the largest possible radius on that sphere and divides the sphere into two equal hemispheres.24) A perfectly round solid where every point on the surface is the same distance from the center. 25) The faces of a solid that are not bases.27) the length of the line segment from the apex to a point on the edge of the base measured along a lateral face (not vertically)28) The perpendicular distance from the base (or base plane) to the opposite vertex, face, or top of a solid29) The sum of the areas of all the lateral faces of a solid
