Question

A rectangular prism with a volume Of ten cubic units is filled with cubes with side lengths 1/2 units. How many 1/2 cubes does it take to fill the prism?

Answer 1

Answer:

80 cubes

Step-by-step explanation:

Volume of cube is equal to product of three sides:

• abh= 10 unit³

Each  side will fit 2 times of 1/2 unit so the volume, if filled with those 1/2 units will be equal to:

• 2a*2b*2h= 8 abh

• 8abh= 8*10 unit³= 80 unit³

So 80 of 1/2 cubes is the answer
