SOLUTION
Part C.
A rectangular prism is a cubiod with a cross section along the length. in a rectangular prism, the opposite faces have equal dimemsion.
Consider the image below.
Hence
The surface of the water will have the same dimemsion as the base of the rectangular prism.
[tex]\begin{gathered} for\text{ the surface of the water, the dimension is } \\ \text{length}=3\text{ ft} \\ \text{width}=1.5ft \end{gathered}[/tex]
Therefore
The dimension of the surface of the water will be
length 3ft and width=1.5ft (3ft by 1.5ft)
