Hello, I Am BrotherEye

28 cubes

Step-by-step explanation:

The answer to part a should by 1/2 inch because the cube must fit within the smallest dimension of the rectangular prism. If the cube were larger, it would not fit inside the 1/2 inch length.

1. Four 1/2 inch cubes would add up to the 2 inch side of the rectangular prism.

2 ÷ 1/2 = 4

2. Seven 1/2 inch cubes would add up to the 7/2 inch side of the rectangular prism.

7/2 ÷ 1/2 = 7

This means that four rows of seven 1/2 inch cubes can fit within the rectangular prism.

3. Multiply.

7 · 4 = 28 cubes
