Find the volume $V$ of a triangular prism if side $a = 12 cm$ and length $l = 20 cm$ .

Answer

$7203 cm^{3}$

Explanation

To find volume $V$ use formula:

V = \frac{3 \cdot a ^{2} \cdot l}{4}

After substituting $a = 12 cm$ and $l = 20 cm$ we have:

V = \frac{3 \cdot 12 cm ^{2} \cdot 20 cm}{4}

V = \frac{144 3 cm ^{2} \cdot 20 cm}{4}

V = \frac{2880 3 cm ^{3}}{4}

V = 7203 cm^{3}
