Question

I did part a and part b please just do part c

Answer 1

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.

`\begin{gathered} for\text{ the surface of the water, the dimension is } \\ \text{length}=3\text{ ft} \\ \text{width}=1.5ft \end{gathered}`

Therefore

The dimension of the surface of the water will be

length 3ft and width=1.5ft (3ft by 1.5ft)
