Question

What is the volume of the triangular prism shown below?

A 960 cu. units
B 240 cu. units
C 480 cu. units
D 720 cu. units

Answer 1

V: L•W•H÷2.
V: 20•6•8 ÷2
V: 960÷2
V: 480

Answer 2

Option C is correct.

Explanation:

Given:

Triangular prism

To find: Volume of the prism.

From figure,

Triangle of the base is a right angled triangle.

Legs of the triangle are 8 units and 6 units

Height of the Prism = 20 units

We know that,

Volume of the prism = Area of the Base × Height

Area of the Base =
`(1)/(2)* Base* Height=(1)/(2)*8*6=24\,units^2`

⇒ Volume of the prism = 24 × 20 = 480 units³.

Therefore, Option C is correct.
