Whakaoti i te I=1/2bh^3

$$I = \frac { 1 } { 2 } b h ^ { 3 }$$

Whakaoti mō b

$$\left\{\begin{matrix}b=\frac{2I}{h^{3}}\text{, }&h\neq 0\\b\in \mathrm{R}\text{, }&I=0\text{ and }h=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{1}{2}bh^{3}=I$$

He hanga arowhānui tō te whārite.

$$\frac{h^{3}}{2}b=I$$

Whakawehea ngā taha e rua ki te \frac{1}{2}h^{3}.

$$\frac{2\times \frac{h^{3}}{2}b}{h^{3}}=\frac{2I}{h^{3}}$$

Mā te whakawehe ki te \frac{1}{2}h^{3} ka wetekia te whakareanga ki te \frac{1}{2}h^{3}.

$$b=\frac{2I}{h^{3}}$$

Whakaoti mō I

$$I=\frac{bh^{3}}{2}$$
