135

Step-by-step explanation:

You have to find the volume of the rectangle first. You need to covert all of the mixed numbers to improper fractions.

2 1/4 = 9/4

1 1/4 = 5/4

A = lwh

9/4(3/4)(5/4)

A = 135/64

Then you find the area of the cube.

A = 1/4(1/4)(1/4)

A= 1/64

Now you divide the product of the two solutions.

To divide fractions, you multiply by the reciprocal.

64 will cancel out

Now you're left with 135.

the equivalent expression are always the hardest ones but you look at the gcf also
