$find the volume of the triangular prism. $42\\ ft^{3}$ $192\\ ft^{3}$ $…$

find the volume of the triangular prism.
$42\\ ft^{3}$
$192\\ ft^{3}$
$84\\ ft^{3}$
$210\\ ft^{3}$

The base is a right triangle, area = $\frac{1}{2} \times 3 \times 4 = 6$ ft²

Volume = base area $\times$ length = $6 \times 14 = 84$ ft³

C. $84\ \text{ft}^3$
