Ber [7]

Answer:

50.24 ft^2

Step-by-step explanation:

Calculating the skid:  

S=\sqrt{30 \times D \times f\times n}\\\\  

   =\sqrt{30 \times 71 \times 0.78\times 0.95}\\\\=\sqrt{1,578.33}\\\\=39.73

Black_prince [1.1K]
You divide one by 1/8 to get the first answer.
It is obvious there are 8 pieces of eight in one whole.
Now to get the amount of eights in three wholes, multiply how much is in one whole by 3 to get 2.
