Mr. Smith has 12 congruent boxes shaped like rectangular prisms in his office. If the length is 25 inches, the height is 2 feet,

Nana76 [90]

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
