Question

find the volume of the prism. round your answer to the nearest tenth, if necessary. 13 m 5 m 3 m

Explanation:

Step1: Find area of triangular base

The area of a triangle $A=\frac{1}{2}\times base\times height$. Here, base = 3 m and height = 5 m. So $A=\frac{1}{2}\times3\times5=\frac{15}{2}$ $m^{2}$.

Step2: Calculate volume of prism

The volume of a prism $V = A\times length$. The length of the prism is 13 m. So $V=\frac{15}{2}\times13=\frac{195}{2}=97.5$ $m^{3}$.

Answer:

$97.5$
