Question

How many 1/2 cm cubes does it take to fill the prisms?

Answer 1

The length of the cubes which are to be filled in the given prism = 1/2 = 0.5 cm

Now we need to arrange the cubes along the sides of the prism.

The length of the prism is 2cm.

Number of cubes that can be arranged on length = 2/0.5 = 4 cubes

The width of the prism is 1cm.

Number of cubes that can be arranged on width = 1/0.5 = 2 cubes

And the height of the prism = 3/2 = 1.5 cm

Number of cubes that can be arranged = 1.5/0.5 = 3 cubes.

The total number of cubes needed to fill the prism

= 4 × 2 × 3

= 24 cubes.

24 cubes of 1/2 cm shall be needed to fill the prism.
