Suppose a building inspector orders the height of a ceiling to be 8 feet tall, but the workers buy lumber that is only 50 centimeters tall. How many pieces of lumber will they have to stack to create an 8-foot ceiling? Explain your answer. (Hint: 1 inch = 2.54 centimeters.)

Respuesta :

Height of the ceiling required is 8 feet

[tex]8 feet = 8 feet * 12 \frac{inch}{1 feet}* 2.54 \frac{cm}{1 inch} [/tex]

[tex] H = 243.84 cm[/tex]

Size of one lumber is 50 cm

so total number of lumbers required for this

[tex]N = \frac{H}{L}[/tex]

[tex]N = \frac{243.84}{50} [/tex]

[tex]N = 4.88 = 5 Lumbers[/tex]

so it requires 5 lumbers
