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

1. 320 cm³
2. 300.5 cm³
3. 310 cm³
4. 300 cm³

Correct Option: A

Area of the base of prism

=	1	(10 + 6) × 5
	2

=	1	× 16 × 5 = 40 sq.cm.
	2

∴ Volume of prism = Area of base × height
= 40 × 8 = 320 cu. cm.
