Answer:
[tex]3 \frac{3}{4}[/tex]
Step-by-step explanation:
We have a right rectangular prism and the question is asking for the volume.
Look for the formula of volume :
V = LWH
L being length
W being width
H being height
The formula is basically saying to multiply all sides together, so let's do as so.
[tex]2*1\frac{1}{4} * 1\frac{1}{2}[/tex]
= [tex]3 \frac{3}{4}[/tex]
