Question

A rectangular prism has a length of 3 1/2 inches, a width of 5 inches, and a height of 1 1/2 inches. What is the volume of the prism? i need it in a fraction plz

Answer 1

Answer: $\frac{385}{4}\ in.^3$

Step-by-step explanation:

Given

Length of prism $L=3\ \frac{1}{2}=\frac{7}{2}\ in.$

Width of prism $w=5\ in.$

Height of prism $h=\frac{11}{2}\ in.$

The volume of a rectangular prism is

$\Rightarrow V=L\times w\times h$

Putting values

$\Rightarrow V=\frac{7}{2}\times 5\times \frac{11}{2}\\\\\Rightarrow V=\frac{385}{4}\ in.^3$

The volume of prism is $\frac{385}{4}\ in.^3$
