ASAP ASAPPPPPPP!!!!!!!!

Answer:
135
Step-by-step explanation:
so we need to find the volume of the rectangle
V= L x W x H
V = [tex]2\frac{1}{4}[/tex] x [tex]\frac{3}{4}[/tex] x [tex]1\frac{1}{4}[/tex] = [tex]\frac{135}{64}[/tex]
so now we need to find the volume of the cubes
V = a^3
1/4^3 = 1/64
so:
135/64 ÷ 1/64 = 135
SO135 CUBES :)
