Question

What is the volume of this triangular prism?20 in3240 in3120 in360 in3

Answer 1

Given the following question:

volume of a prism = (height × base × length) ÷ 2

height = 4

base = 5

length = 12

`\begin{gathered} v=(4*5*12)/2 \\ 4*5=20 \\ 20*12=240 \\ 240/2=120 \\ =120in^3 \end{gathered}`

Third option is your answer.
