a) Surface area:

b) Volume:

Step-by-step explanation:

a)

The surface area of the prism is the sum of the areas of all its faces.

The lengths of the sides of the prism are:

where b, w and h are the base, width and height, respectively.

Therefore there are 2 faces (top and bottom) with area:

Then there are 2 faces (left and right) with area:

And then, there are 2 faces (front and back) with area:

And so, the total surface area is

b)

The volume of a rectangular prism is given by

where

b is the base

w is the width

h is the heigth

For the rectangular prism in this problem, we have:

b = 4 ft (base)

w = 2 ft (width)

h = 3 ft (height)

Therefore, the volume is

50x5=$250
