How many cubes with side lengths of 1/2 cm does it take to fill the prism? Height: 3/2 cm Width:1 cm length: 2 cm
Irina18 [472]

Answer:

24

Step-by-step explanation:

If we want to cover the base of the prism having dimensions 2 cm × 1 cm with \frac{1}{2} cm length of cube, then there will be (4 × 2) = 8 cubes that can occupy the base.

Width is 1 cm, so there can fit 2 cubes of length \frac{1}{2} cm and length is 2 cm, where 4 cubes of length \frac{1}{2} cm can fit. So, in total (4 × 2) = 8 cubes of \frac{1}{2} cm length.

Now, height of the prism is \frac{3}{2} cm where 3 cubes of length \frac{1}{2} cm can fit.

Therefore, in total there can be (8 × 3) = 24 cubes of \frac{1}{2} cm length. (Answer)
