The volume of a rectangular prism is 72 cubic centimeters. The prism is 2 centimeters wide and 4 centimeters high. What is the l
skelet666 [1.2K]

Answer:

The length of prism is  <u>9 centimetres</u>.

Step-by-step explanation:

Given:

The volume of a rectangular prism is 72 cubic centimeters.

The prism is 2 centimeters wide and 4 centimeters high.

Now, to find the length of prism:

Let the length be l.

Width = 2 centimeters.

Height = 4 centimeters.

Volume = 72 cubic centimeters.

So, putting the formula to get the length of prism:

Volume = length\times width\times height

72=l\times 2\times 4

72=l\times 8

Dividing both sides by 8 we get:

9=l

Length = 9 centimetres.

Therefore, the length of prism is  9 centimetres.

Answer:

  • Annie- 17 hours, Brian- 3 hours

Step-by-step explanation:

Let the number of hours Annie travelled be a, and same of Brian be b

<u>Then we have</u>

  • a + b = 20
  • a = 5b + 2

<u>Substituting a in the first equation</u>

  • 5b + 2 + b = 20
  • 6b = 20 - 2
  • 6b = 18
  • b = 3

<u>Then finding a</u>

  • a = 20 - 3 = 17

<u>So the answer is:</u>

  • Annie- 17 hours, Brian- 3 hours
