What is the Formula for finding trapeziums volume?
A trapezium is a two dimensional figure. It can be said to have 0 or infinite height, therefore the volume of all trapezia is 0 or infinite. The area of a trapezium can be found by the multiplying the mean average of the parallel sides by the perpendicular height between them. If a and b are the lengths of the parallel sides, and h is the perpendicular height between them, then: area_trapezium = ½(a + b) × h If you have a trapezoidal prism, then its volume is given by the area of the trapezia at the ends multiplied by the length (l) between them: volume_trapezoidal_prism = ½(a + b) × h × l
What is a shape with four sides and four angles?
A quadrilateral, which includes squares, rhombi, parallellograms and trapezia...
How many different types of trapeziums are there?
There are infinitly many types. However some broad (and not necessaryly exclusive) classes of trapezia are Right trapezia (with at least 1 right angle) Isoceles trapeziea (the non parallel sides are equal in length) parallelograms (both pairs of sides are parallel)
What shapes have perallel opposite sides?
-- every parallelogram (including rectangles, squares, and rhombera)-- trapezia (trapezoids)-- every regular polygon with an even number of sides
What are the vertical and horizontal cross sections of a rectangular pyramid?
The vertical cross sections are trapezia or triangles. The horizontal cross sections are rectangles which are mathematically similar to the base.
