Answer:
120 cubes will fill the prism
Step-by-step explanation:
The given dimensions of the prism are
1.25" x 1" x 1.5"
Each cube 0.25"
Along the 1.25" edge we can stack 1.25/0.25 = 5 cubes
Along the 1" edge we can stack 1/0.25 = 4 cubes
Along the 1.5" edge we can stack 1.5/0.25 = 6 cubes
Total number of cubes to fill the prism
= 5 x 4 x 6
= 120
Therefore 120 cubes of side 0.25" will fill the prism
