How many side pieces 8 1/4 inches long and 6 3/4 inches wide can mr. Penny cut from a wooden plank 9 5/8 feet long and 9/16 foot wide

Respuesta :

Answer:Total number of side pieces [tex] = 14[/tex]


Step-by-step explanation:


To find the number of side pieces we use formula = [tex] \frac{Area of wooden plank}{Area of 1 side piece} [/tex]


Area of wooden plank [tex]= length \times width[/tex]


Length of wooden plank [tex] =\frac{77}{8}feet =\frac{77}{8} \times 12 [/tex] inches

Length [tex] = \frac{231}{2} [/tex] inches


Width of plank [tex] = \frac{9}{16} foot = \frac{9}{16} \times 12 =\frac{27}{4}[/tex] inches


Area of plank[tex]= \frac{231}{2} \times \frac{27}{4} [/tex] sq inches


Area of 1 side piece [tex]= \frac{33}{4} \times \frac{27}{4}[/tex] sq inches

Now using formula


Number of pieces [tex]= \frac{Area wooden plank}{Area of 1 side piece} [/tex]


[tex] =(\frac{231}{2} \times \frac{27}{4} )\div (\frac{33}{4} \times \frac{27}{4}) [/tex]


Converting division into multiplication we get,


[tex] =(\frac{231}{2} \times \frac{27}{4} )\times (\frac{4}{27} \times \frac{4}{33} )[/tex]


On solving we get


[tex]= 14[/tex]


Total number of side pieces [tex] = 14[/tex]
