Help please! I don't really get this.

Boxes from top to bottom

Sides

6

6

12

52

Step-by-step explanation:

1) Split the prism into individual sides.

2) Find the area of each side by multiplying length by height.

3) Add the areas together.

    Since this is a rectangular prism; the top & bottom of the box will have the same area. Same with the other sides.

    The top of the box is 2 by 3 making the area 6 times 2 for the bottom is 12

    The left and right sides are 3 by 4  A = 12 times 2    24

    The front and back are 2 by 4  A=8 times 2              16

    24 + 16 + 12

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
