Answer:

There are three decimal places in the final answer.

Step-by-step explanation:

We have to calculate the expression 4.2 × 12.3 × 14.6, in which the floor dimensions are 12.3 ft by 14.6 ft. which I have to cover with tiles and each square foot of tile costs $4.20.

So, the area of the floor is (12.3 × 14.6) sq. ft. = 179.58 square feet.

Now, the cost of covering the floor with tiles will be = $(179.58 × 4.2) = $754.236.

Therefore, there are three decimal places in the final answer. (Answer)
