Answer 2

Answer:

1408 square tiles

Step-by-step explanation:

She is basically tiling the surface area of a rectangular prism that is 24 by 16 by 8 inches long. A rectangular prism has 6 sides total. Here, the sides are:

24 by 16

24 by 16

16 by 8

16 by 8

24 by 8

24 by 8

So basically, Each length is multiplied by another length 2 times each. We need to add all of these lengths together:

(24 * 16) + (24 * 16) + (16 * 8) + (16 * 8( + (24 * 8) + (24 * 8) = (384 + 384) + (128 + 128) + (192 + 192) = 768 + 256 + 384 = 1408
