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

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.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
