Find the number of chips needed to make each rectangle prism
Tom [10]

1.

height= 3

length= 5

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

3 x 5 x 4 = 60

We need 60 blocks

2

height= 4

length= 6

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

4 x 6 x 4 = 96

We need 96 blocks

3

height= 2

length= 3

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

2 x 3 x 4 = 24

We need 24 blocks

4

height= 4

length= 8

width= 6

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

4 x 8 x 6 = 192

We need 192 blocks

5

height= 2

length= 6

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

2 x 6 x 4 = 48

We need 48 blocks

6

height= 1

length= 5

width= 3

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

1 x 5 x 3 = 15

We need 15 blocks

Part C of Jim and his dad are building a rectangular flower bed.
charle [14.2K]

The perimeter is 35. If we were to change the width, which is one of the dimensions of the flower bed, The perimeter will change. This means that perimeter will no longer be 35. So in order to keep the perimeter as it is, if we change one dimension, we must also change the other.

Let's solve for the length, using the formula to see how much the length changes from.

p = 2l + 2w

35 = 2l + 2(15)

35 = 2l + 30

5 = 2l

2.5 = l


We must increase the length from 2.5 feet. This is because decreasing one dimension will decrease the perimeter. But if we increase the other dimension as well, it will restore the perimeter to where is was initially.

- Maria wants to buy a ring that costs $67.00. She has a coupon for 25% off.
Vilka [71]

Answer:

$16.75

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 67 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 67 is 100%, so we can write it down as 67=100%.

4. We know, that x is 25% of the output value, so we can write it down as x=25%.

5. Now we have two simple equations:

1) 67=100%

2) x=25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

67/x=100%/25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 25% of 67

67/x=100/25

(67/x)*x=(100/25)*x       - we multiply both sides of the equation by x

67=4*x       - we divide both sides of the equation by (4) to get x

67/4=x

16.75=x

x=16.75

now we have:

25% of 67=16.75
