Question

How do you find volume with fractional edge lengths?

Answer 1

Step1. Defining edges

Edges is define for the figure which corner like triangle, rectangle, cube , cuboid etc.

Step2. Defining volume.

volume is define for the three dimension figure like cube cuboid and given by area of the base multiply by height

.$$\begin{gathered} \mathit{l}\mathbf{\times }\mathit{b}\mathbf{\times }\mathit{h}where\mathbf{}\mathit{l}\mathbf{=}\mathbf{}\mathit{l}\mathit{e}\mathit{n}\mathit{g}\mathit{t}\mathit{h} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathit{b}\mathbf{=}\mathit{b}\mathit{r}\mathit{e}\mathit{a}\mathit{d}\mathit{t}\mathit{h} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathit{h}\mathbf{=}\mathit{h}\mathit{e}\mathit{i}\mathit{g}\mathit{h}\mathit{t} \end{gathered}$$

Step3. Finding value with fractional edge length.

Consider the edge length $5cm,\frac{3}{2}cm\&\frac{12}{5}$

Then volume (V)

$\begin{array}{rcl}v& =& 5\times \frac{3}{2}\times \frac{12}{5}\\ & =& 18c{m}^3\end{array}$

Hence, in this way we can calculate the volume of fractional edge length.
