Answer:
he isn't
Step-by-step explanation:
The wood has dimensions of 18 x 12
If He wants the tray to have a height of 2, subtract 2 x 2 from both the length and the width
18 - 4 = 14
12 - 4 = 8
the highest possible dimensions of the tray can be 14 x 8
10 1/2 x 10 1/2 is greater than 14 x 8. so he is not correct
