The base of a right prism is a trapezium whose lengths of two parallels sides are 10 cm and 6 cm and distance between them is 5 cm. If the heights of the prism is 8 cm, its volume is :

A. 320 cm3

B. 300 cm3

C. 310 cm3

D. 300.5 cm3

Answer: Option A

Solution(By Examveda Team)

Length of parallel sides of prism = 10 cm and 6 cm
Height of prism = 8 cm
∴ Volume of prism :
$$\eqalign{ & = \frac{1}{2}\left( {10 + 6} \right) \times 5 \times 8 \cr & = \frac{1}{2} \times 16 \times 5 \times 8 \cr & = 320{\text{ c}}{{\text{m}}^3} \cr} $$
