Answer:
width of one box = 1.25 inches
Step-by-step explanation:
Given data:
12 congruent boxes
Length = 25 inches
height = 2 feet
Volume = 9000 cubic inches
First change the height into inches
1 foot = 12 inches
therefore 2 feet = 24 inches
Volume = Length * width * height
9000 = 25 * width * 24
9000 = 600 * width
width = 9000/600
width = 15 inches
width of one box = width of all boxes / number of boxes
width of one box = 15/12
width of one box = 1.25 inches
Answer:
No
Step-by-step explanation:
Relatively prime means that the only common factor the 2 numbers share is 1
factors of 16 are 1, 2, 4, 8, 16
factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40
common factors are 1, 2, 4, 8
Hence 16 and 40 are not relatively prime
