2 5/8 × 4 = 10 1/2
Charlie does not have enough wood because 10 1/2 is also equal to 10 4/8 and Charlie only has 10 3/8

Answer:
when a expression is squared (²) that means it is multiplyed by itself.
Step-by-step explanation:
(1/2)² = (1/2 x 1/2)
1 squared = 1
2 squared = 4
1/4 is smaller than 1/2. 1/2 is greater than (1/2)²
