Complete Question
Rectangular prism with the value of 10 cubic units is filled with cubes the side lengths of 1/2 unit how many 1/2 unit cubes does it take to fill the prism?
Answer:
80 cubes
Step-by-step explanation:
Step 1
The volume of a cube = (side length)³
From the above question, the side length of the cube = 1/2 unit
Hence, the volume of the cube = (1/2 unit)³
= 1/8 cubic units
Step 2
Rectangular prism with the value of 10 cubic units.
The number of 1/2 unit cubes that it takes to fill the prism is calculated as:
10 cubic units ÷ Volume of 1/2 unit cubes
= 10 cubic units ÷ 1/8 cubic units
= 10 × 8/1
= 80 cubes.
Therefore, number of 1/2 unit cubes that it takes to fill the prism is 80 (1/2 units) cubes

Step-by-step explanation:
Answer:
(3, -1)
x is 3
y is -1
Step-by-step explanation:
Solving for x:
2x+y=5
<em>Subtract y from both sides</em>
2x= -y+5
<em>Subtract 5 from both sides</em>
2x-5= -y
<em>Multiply both sides by 4</em>
8x-20= -4y
5x+4y=11
<em>Subtract 4y from both sides</em>
5x= -4y+11
<em>Subtract 11 from both sides</em>
5x-11= -4y
<u>Combine equations:</u>
5x-11=8x-20
<em>Subtract 5x from both sides</em>
-11=3x-20
<em>Add 20 to both sides</em>
9=3x
3x=9
<em>Divide both sides by 3</em>
x=3
Solving for y:
2x+y=5
<em>Subtract y from both sides</em>
2x= -y+5
-y+5=2x
<em>Multiply both sides by 5</em>
-5y+25=10x
5x+4y=11
<em>Subtract 4y from both sides</em>
5x= -4y+11
-4y+11=5x
<em>Multiply both sides by 2</em>
-8y+22=10x
<u>Combine equations:</u>
-8y+22= -5y+25
<em>Add 8y to both sides</em>
22=3y+25
<em>Divide both sides by 25</em>
-3=3y
3y= -3
<em>Divide both sides by 3</em>
y= -1
