You can find the volume of a rectangular solid using the formula Volume=Length.width.height, or V=lwh. Find the volume of the rectangle solid pictured here! 5,3,7

Answers

The volume of the rectangular solid is 105 cubic units. A rectangular solid is a three-dimensional shape with six rectangular faces.

To calculate its volume, we use the formula:

Volume (V) = Length (l) × Width (w) × Height (h)

To find the volume of the rectangular solid (rectangular prism) with dimensions of length = 5 units, width = 3 units, and height = 7 units, we can use the formula:

Volume (V) = Length (l) * Width (w) * Height (h)

V = 5 * 3 * 7

V = 105 cubic units

The units are multiplied together since volume is a measure of three dimensions (length × width × height). In this case, the units are given in "units," so the final volume is expressed in "cubic units."

So, the volume of the rectangular solid is 105 cubic units.

Richard has four times as many marbles as john. if Richard have 18 to John they would have the same number. how many marbles has each?

Answers

Answer:

The number of marbles Richard has 24 and John has 6.

Step-by-step explanation:

Richard has four times as many marbles as john.

If Richard have 18 to John they would have the same number.

Now, to find number of marbles each has.

Let the marbles of John be $x$ .

And the marbles of Richard be $4x.$

According to question:

$4x=x+18.$

Subtracting both sides by $x$ we get:

$3x=18.$

Dividing both sides by 3 we get:

$x=6.$

Marbles of John = $6.$

Marbles of Richard = $4x=4* 6=24$

Therefore, the number of marbles Richard has 24 and John has 6.

In a machine, a large gear completes a revolution every minute while a small gear completes a revolution every 24 seconds. If the gears are currently aligned, how much time will pass before they are aligned again?

Answers

This question is asking you for the least common multiple of 60 (seconds in 1 minute) and 24 (seconds in 24 seconds).
I think it's 120 (you should check it) and that would be 3 minutes.

the distance between Columbus Ohio and New York City is about 560 miles how many hours would it take the train to travel between cities

Answers

The number of hours the train took to travel between the two cities is 2.09 hours.

Given that,

The distance between Columbus, Ohio, and New York City is about 560 miles.

And, The train travels 268 miles an hour.

We need to find out how many hours would it take the train to travel between the two cities.

Here, the train speed is,

= 268 miles per hour

And, the distance between the two cities.

= 560 miles

We have,

268 miles = 1 hour

Multiply both sides by 560

560 x 268 miles = 560 x 1 hour

Divide both sides by 268

560 miles = (560/268) x 1 hour

560 miles = 2.09 hours

Hence, the train will take 2.09 hours to travel 560 miles,
