The problem does not ask for volume or total surface area, hence, until the request of the problem will be provided, you may evaluate the followings:

TSA (total surface area) = 3*Area of side + 2*Area of base

The sides of prism are rectangles, hence you need to use the following formula to evaluate the area:

A = length*width `= 14*8 = 112 ft^2`

The base of prism is equilateral triangle, hence you need to use the following formula to evaluate the area:

`A = (l^2*sin 60^o)/2 =gt A = 64*sqrt3/4`

`A = 16*sqrt3 ft^2`

`TSA = (112 + 16*sqrt3) ft^2`

You need to evaluate the volume of right triangular prism such that:

V = A of  base*height

`V = 16*sqrt3*14 =gt V = 224sqrt3 ft^3`

Hence, evaluating the TSA and Volume of prism yields `TSA = (112 + 16*sqrt3) ft^2`  and `V = 224sqrt3 ft^3` .
