Answer 1

Answer:

26.25 or 26 1/4

Step-by-step explanation:

Formula for rectangular prism:

$V=lwh$

Substitute in our known values:

V=3.5(5)(1.5)

solve

V=26.25

The volume is 26.25 (decimal form) or 26 1/4.

Hope this helps! :)

Answer 2

Answer: 26.25 in³

Step-by-step explanation:

Given volume formula for a rectangular prism:

     V = LWH

First, I am going to turn the $\frac{1}{2}$s into 0.5 to make it easier to multiply using a calculator. 3 and one-half becomes 3.5 and 1 and a half becomes 1.5.

Substitute known values and solve by multiplying.

     V = LWH

     V = (3.5 in)(5 in)(1.5 in)

     V = 26.25 in³
