Complete the following pythagorean identity sin(0)2+. =1

The correct question is
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? Enter your answer in the box as a simplified mixed number or a decimal.

we know that
length=3 1/2 in> (3*2+1)/2=7/2 in
width= 5 in
height=1 1/2 in> (1*2+1)/2=3/2 in

[volume of the prism]=[length]*[width]*[height]
[volume of the prism]=[7/2]*[5]*[3/2]=105/4 in³> 26.25=26 1/4 in³

the answer is 26 1/4 in³
