G6 Chapter 13: Perimeter and Area Flashcards

A collection of mathematical vocabulary and formulas focused on perimeter, area, volume, and geometric relationships from the Grade 6 Chapter 13 worksheet.

Volume of rectangular prisms

The formula used to calculate the 3D space of a rectangular prism, defined as $V = L \times W \times h$ (length $\times$ width $\times$ height).

Area of a trapezoid

The formula used to find the area of a four-sided figure with one pair of parallel sides, defined as $A = \frac{(b_1 + b_2) \times h}{2}$.

Surface Area ($S.A.$) of a triangular prism

The total area of the outer surfaces of a triangular prism, calculated using the formula $S.A. = (S_1 + S_2 + S_3) \times L + bh$.

Relationship between Pencils ($p$) and Boxes ($b$)

Given a table where $p$ values are $12, 24, 36, 48$, the relationship is expressed by the equation $p = 12b$.

Area of a regular polygon

The total area determined by multiplying the area of one triangle by the total number of sides, expressed as $A = \text{Area of one triangle} \times \text{number of sides}$.

Missing dimension (height) of a trapezoid

The formula used to solve for the height ($h$) when the area ($A$) and both bases ($b_1, b_2$) are known: $h = \frac{2A}{b_1 + b_2}$.

Triangular prism height ($h$)

A dimension used in surface area calculations, representated as $h = \text{height}$, distinct from terms like $b = \text{base}$ and $L = \text{length}$.
