To find the volume of a triangular prism, you can use the formula: \[ V = \text{Base Area} \times \text{Height} \] First, we need to calculate the area of the triangular base. Since it is an equilateral triangle with side length \( s = 8 \mathrm{in} \), you can use the formula for the area of an equilateral triangle: \[ \text{Area} = \frac{\sqrt{3}}{4} s^2 \] Substituting the side length: \[ \text{Area} = \frac{\sqrt{3}}{4} (8)^2 = \frac{\sqrt{3}}{4} \times 64 = 16\sqrt{3} \mathrm{in}^2 \] Now, plug this area into the volume formula: \[ V = 16\sqrt{3} \times 6 = 96\sqrt{3} \mathrm{in}^3 \] Therefore, the volume of the triangular prism is approximately \( 166.28 \mathrm{in}^3 \) when you evaluate \( 96\sqrt{3} \).
