Answer:
48 cubes
Step-by-step explanation:
A rectangular prism with a volume of 6 cubic units is filled with cubes with side lengths of 1/2 units . how many 1/2 unit cubes does it take to fill the prism
Solution
Volume of a cube=b^3
Where,
b=side length of a cube
b=1/2 units
Volume of a cube=b^3
=(1/2)^3
=1/8 cubic units
Volume of the rectangular prism=6 cubic units
To find out the number of cubes needed to fill the prism, divide the volume of the rectangular prism by the volume of one cube
Number of cubes needed= Volume of the rectangular prism ÷ volume of a cube
=6 ÷ 1/8
=6 × 8/1
=48 cubes
