The cards Question What is the net of a 3D object? Tap to flip Answer A 2D representation of its surfaces that can be folded up into the 3D object. Question What kind of shapes is a net composed of? Tap to flip Answer Polygons. Question If a net has the correct face shapes, will it always fold into the desired solid? Tap to flip Answer No; the edges that join on folding must also match, so the faces must be arranged correctly. Question What is volume? Tap to flip Answer The amount of space occupied by a closed 3D shape. Question What is a prism? Tap to flip Answer A polyhedron with a polygon base and an identical parallel opposite face, with corresponding edges joined by parallelograms. Question How do you find the volume of a prism? Tap to flip Answer Multiply the area of the cross-section by the length. Question The volume of a 3D shape comes from the product of how many perpendicular lengths? Tap to flip Answer Three. Question What is surface area? Tap to flip Answer The total area of all the surfaces of a closed 3D shape, including all faces and any curved surfaces. Question How many faces must be included in the surface area of a cuboid? Tap to flip Answer All six. Question Can the surface area of a cuboid be found without drawing its net? Tap to flip Answer Yes. Question How is the surface area of a prism found? Tap to flip Answer By summing the areas of all its faces. Question What is a cylinder? Tap to flip Answer A 3D shape with a circular base and an identical parallel opposite face. Question A cross-section of a cylinder made parallel to the base is congruent to what? Tap to flip Answer The base. Question Is a cylinder a prism? Tap to flip Answer No, but it has a similar structure. Question From which formula can the volume of a cylinder be derived? Tap to flip Answer The formula for the volume of a prism. Question What helps deduce the formula for the surface area of a cylinder? Tap to flip Answer Drawing the net of the cylinder. Question If a cylinder's measurements are given in different units, what should you do before calculating? Tap to flip Answer Convert all the measurements to the same unit. Question What is a pyramid? Tap to flip Answer A 3D shape with a polygonal base and triangular faces that meet at an apex. Question What is the apex of a pyramid? Tap to flip Answer The vertex at the greatest perpendicular distance from the base. Question What is a right pyramid? Tap to flip Answer A pyramid whose apex lies directly above the centre of the base. Question What is an oblique pyramid? Tap to flip Answer A pyramid whose apex is not directly above the centre of the base. Question What shape are the side faces of a pyramid? Tap to flip Answer Triangles. Question Why is a cone not a pyramid? Tap to flip Answer A pyramid has a polygonal base, but a cone's base is a circle, which is not a polygon. Question In most pyramids, why can a slanted edge not be used as the height in a volume calculation? Tap to flip Answer The edge is not perpendicular to the base; volume multiplies three perpendicular lengths. Question What is a sphere? Tap to flip Answer A 3D shape where every point on its surface is the same distance from the centre. Question Which constant is often forgotten in the formula for the surface area of a sphere? Tap to flip Answer 4 Question Give one way the volume of a sphere can be found without a formula. Tap to flip Answer By displacement: put it into a cylinder filled with water; its volume is the difference between the cylinder's volume and the water's. Question In the volume of a sphere formula, what must be done to the radius before multiplying by the constants? Tap to flip Answer Cube it. Question What is a circular cone? Tap to flip Answer A 3D shape with a circular base and one curved surface narrowing from the base to an apex. Question In a right circular cone, how does a line through the apex and the centre of the base meet the base? Tap to flip Answer Perpendicular to it. Question What is the area of the slanted surface of a cone? Tap to flip Answer πrl Question What is the total surface area of a cone? Tap to flip Answer πrl + πr² Question The slanted surface of a cone, cut into congruent triangles, forms which shape? Tap to flip Answer A parallelogram, with dimensions of the slanted length and half the circumference of the base. Question From which two measurements can the slanted length of a cone be calculated? Tap to flip Answer The height of the cone and the radius of the base. Question Which height of a cone is needed for its volume: slant or perpendicular? Tap to flip Answer The perpendicular height. Question Which height of a cone is needed for its curved surface area: slant or perpendicular? Tap to flip Answer The slant height. Question What is a solid? Tap to flip Answer A shape that has three dimensions. Question What is a compound shape? Tap to flip Answer A shape created using two or more basic shapes. Question What is another word for a compound shape? Tap to flip Answer A composite shape. Question When finding the surface area of a composite solid, what must be left out? Tap to flip Answer The overlapping faces. Question Give one method for finding the volume of a composite solid. Tap to flip Answer E.g. decompose it into parts, complete the solid, or decompose and rearrange its parts. Question If a problem refers to packaging or painting a shape, which calculation is needed? Tap to flip Answer Surface area.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
