A rectangular prism has a volume of 240 cubic feet. If the length is 4 feet and the width is 4 feet, what is the height of
frosja888 [35]

Answer:

Let's use the formula for the volume of a rectangular prism;

V = l · w · h

Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)

<u>What we know:</u>

  • Volume = 240 ft
  • Length = 4 ft
  • Width = 4 ft

<u>What we need to find out:</u>

  • Height

Let's plug in what we know into the formula:

V = l · w · h

<u>240</u> = <u>4</u> · <u>4</u> · h

Now let's solve for h:-

240 = 16 · h

240 = 16h

Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.

÷16    ÷16

Finally, you would end up with a result of:

<u>15</u> = h

Hence, the height of this prism is <u>15 feet</u>.

If 10 + 5x is 12 more 8, what is the value of 3x?
vredina [299]

Answer:

3x=6

Step-by-step explanation:

10 + 5x =8+12

10 +5x = 20

Subtract 10 from each side

10-10+5x=20-10

5x= 10

Divide by 5

5x/5 = 10/5

x = 2

We want 3x

3(2) = 6

3x=6
