Answer:
Option C is correct
[tex]488\frac{1}{4} m^3[/tex]
Step-by-step explanation:
Volume(V) of a right rectangular prism is given by:
[tex]V = lwh[/tex]
where
l is the length, w is the width and h is the height of the prism respectively.
as per the statement:
A right rectangular prism is 10 1/2 m wide, 15 1/2 m long, and 3 m tall.
⇒[tex]w = 10\frac{1}{2}=10.5 m[/tex], [tex]l = 15\frac{1}{2} = 15.5 m[/tex] and h = 3m
Substitute these in [1] we get;
[tex]V = (10.5) \cdot 15.5 \cdot 3 = 488.25 m^3[/tex]
Therefore, the volume of the prism is, [tex]488.25 = 488\frac{1}{4} m^3[/tex]
