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.
Answer:
y=2.9
Step-by-step explanation:
3(2y - 0.3) = 19.4 - y
6y-0.9=19.4
6y+y-0.9=19.4
6y+y=19.4+0.9
7y=19.4+0.9
7y=20.3
7y/7=20.3/7 (divid each one by seven. that's what /7 means)
y=2.9
1. (5 + 4) x 2 + 6 - (2 x 2) - 1
2. 9 x 2 + 6 - 4 - 1
3. 18 + 6 - 4 - 1
4. 24 - 4 - 1
5. 20 - 1
6. 19
