Estimate the number of basketballs it would take to fill your classroom (for distance students your “classroom” can be whatever room you use to watch the lectures). State any assumptions you make. Specify how many significant figures you think are appropriate for your answer.
Homework Answers
Assume the dimensions of the room
Length L = 10 ft
Width W = 10 ft
Height H = 10 ft
Volume of room V = L x W x H
= 10 ft x 10 ft x 10ft
= 1000 ft3
Dia of basket ball D = 9.55 in x (1ft/12in) = 0.79583 ft
Volume of basket ball Vb = (4/3)*3.14*(D/2)^3
= (4/3)*3.14*(0.79583/2)^3
= 0.26378 ft3
Number of basketballs = V/Vb
= 1000/0.26378
= 3791
4 significant figures are sufficient to deal with this problem because number of basketballs can be fit in a room is in thousands.

For this discussion forum, we will share grade-appropriate books that promote multicultural awareness and appreciation. Using APA format, state one book that you think would be useful in teaching multicultural awareness to primary grade (grades one through three) children. State why you chose the book, including how it fits the developmental characteristics of primary grade students. Based on your selected book, explain one learning objective related to teaching multicultural awareness appropriate for primary grade children. Design one follow-up activity that...

If you used only a keyboard to enter data, how many years would it take to fill up the hard drive in a computer that can store 1.2 terabytes (1 terabyte = 1.0 × 1012 bytes) of data? Assume 40-hour work weeks, that you are typing 50 weeks in a year, and that you can type 180 characters per minute, and that one byte is one keyboard character. Express your answer using two significant figures.
