A concrete pile from a waterfront pier was pulled from the harbor water at port hueneme california. It's dimensions we're 14in x
Anna [14]

The surface area expressed in square feet of a single face of a pile is 1.45 square feet.

<u>Explanation:</u>

The dimensions of the pillar are given as 14 in \times 14 in

(1 feet = 12 inch)

According to the pillar dimensions mentioned in the problem, the length of the pillar should be 15 inches, height by 14 inches and the width by 14 inches.

There will be two surface areas of the concrete pile, one implies side surface area and the other is end surface area.

For calculating the side surface area,

Area of the side surface = 14 in \times 15 in

                                         = 14 in. \times  \frac{1 ft.}{12 in.}

                                         = 1.16 \times 1.25

                                         = 1.45 square feet.

(In the given question, only a single face is asked so there is no need to find the surface area of the end face.)

Which of the following is a major difference between lactic acid and alcohol fermentation?
pishuonlain [190]

Both lactic acid and alcoholic fermentation begin with pyruvic acid and nadh. they are anaerobic processes that result in the production of energy in the absence of oxygen. So basically the two differences are that one makes ethanol and one makes lactic acid, and the other is that they are made by different species.


Alcohol fermentation requires aerobic conditions, while lactic acid fermentation requires anaerobic conditions.
