Answer:

  • 648

Step-by-step explanation:

<u>If the number is xyz, we have:</u>

  • x = 1 to 9, total 9 ways
  • y = 0 to 9, total 10 ways minus 1 to prevent repetition, so 9 ways
  • z = 0 to 9, total 10 ways minus 2 ways to prevent repetition, so 8 ways

<u>Total number of possible 3-digit numbers:</u>

  • 9*9*8 = 648

Yolanda makes wooden boxes for a crafts fair, She makes 100 boxes like the one shown, and she wants to paint all the outside fac
Gemiola [76]

A box has 4 sides, two short sides which are width by height and two long sides which is length by height.

A) Surface area = 2(LxH) + 2(WxH)

Surface area = 2(10x4) +2(6x4)

Surface area = 2(40) +2(24)

Surface area = 80 + 48

Surface area = 128 square inches for each box.

128 square inches x 100 boxes = 12,800 square inches.

B) 1 can covers 14,000 square inches which is greater then the total of the 100 boxes, so she will need to buy 1 can of paint.
