Height of a prism-shaped part of a machine is 8 cm and its base is an isosceles triangle, whose each of the equal sides is 5 cm and remaining side is 6 cm. The volume of the part is

Answer: Option B

Volume of the part (prism) = Area of base × height
Area of base (Isosceles Δ)
$$\begin{array}{rl}& =\frac{b}{4}\sqrt{4a^2-b^2}\\ & =\frac{6}{4}\sqrt{4{\left(5\right)}^2-{\left(6\right)}^2}\\ & =12\text{ c}{\text{m}}^2\end{array}$$
Volume of prism = 12 × 8 = 96 cm³
