James says: "This is glossary of terms for UK KS3 Maths,[ages 11-13] taken Works quite well with a 'random glossary entry' html block on a main course page since the definitions are in a small font size.

Cube1. In geometry, a three-dimensional figure with six identical, square faces. Adjoining edges and faces are at right angles. 2. In number and algebra, the result of multiplying the same value by itself, then by itself again. Example: 2 x 2 x 2 is written a 23. This is said as '2 cubed', or '2 to the power of three'. | |
Cube NumberA number that can be expressed as the product of three equal integers. Example: 27 = 3 x 3 x 3. 27 is therefore a cube number. So are 1, 8, 56, etc... | |
Cube Root
A value or quantity whose cube is equal to a given quantity. Example: the cube root of 8 is 2 since 2 x 2 x 2 = 8. | |
CubicAdjective to describe a mathematical expression of degree three, i.e. with a power equal to 3. A cubic polynomial is one of the type ax3 + bx2 + cx +d, where the highest power is equal to 3. The coefficients b,c, and d could equal zero which would just leave the cubic term. | |
Cubic CentimetreSymbol: cm3. A unit of volume. The three-dimensional space equivalent to a cube with edge length 1cm. | |
Cubic CurveA curve described by an algebraic equation containing at least one cubic term, i.e. a term raised to the power of three, and no terms with higher powers than three. | |
Cubic MetreSymbol: m3. A unit of volume; a three-dimensional space equivalent to a cube of edge length 1m. | |
CuboidA three-dimensional figure with six rectangular faces. Different to a cube in that the lengths of the sides are not necessarily the same; a 3D rectangle. | |
Cumulative Frequency DiagramA graph for displaying cumulative frequency. At a given point on the horizontal axis the sum of the frequencies of all the values up to that point is represented by a point. These graphs always curve upwards because the vertical co-ordinates will be proportional to the sum of frequencies, which can't decrease. | |
