Question

a triangular prism has a base with a length of 6 in and a height of 8 cm. the height of the whole prism is 12 cm. What is the volume of the triangular prism?

Answer 1

The volume of a prism of this type is 

v= (1/2) x B x h x H 

(1/2) x 15.24 x 8 x 12

= 732

Answer 2

The volume formula for a rectangular prism is 1/2bhl.
First you have to convert 6 in. into cm. Which is 15.24
Next you multiply 1/2bhl.
1/2 (15.24)(12)(8)
The answer is 731.52 or 731.5 rounded.
