Step-by-step explanation:

a box (like a "deformed" die) has 6 sides.

and in case of such a rectangular box there are 3 pairs of equal sides.

the area of each side is a rectangle.

top and bottom : 19×12 times 2

front and back : 19×3 times 2

left and right : 12×3 times 2

so, we get

19×12×2 + 19×3×2 + 12×3×2 = 642 in²

and now, we need 10% more.

10% = 642/10 = 64.2 in²

the total is then

642 + 64.2 = 706.2 ≈ 706 in²

Aleksandr-060686 [28]

Answer:

There may be 1 or 3 tricycles in the parking lot.

Step-by-step explanation:

Since at any point in time, there could be bicycles, tricycles, and cars in the school parking lot, and today, there are 53 wheels in total, if there are 15 bicycles, tricycles, and cars in total, to determine how many tricycles could be in the parking lot, the following calculation must be performed:

13 x 4 + 1 x 3 + 1 x 2 = 57

11 x 4 + 1 x 3 + 3 x 2 = 53

10 x 4 + 3 x 3 + 2 x 2 = 53

8 x 4 + 5 x 3 + 2 x 2 = 51

10 x 2 + 1 x 3 + 4 x 4 = 39

9 x 3 + 1 x 2 + 5 x 4 = 49

Therefore, there may be 1 or 3 tricycles in the parking lot.

yKpoI14uk [10]
So,

If she keeps one-fourth for herself, she will keep:
72 * 0.25 = 18

That leaves the rest for her friends.
72 - 18 = 54

Her friends will get 54 "Suites."
