What is a cube?

It is a polygon having six faces.

The volume of a cube is side cube.

We have,

To divide the 360 unit cubes equally among 8 groups, we need to perform the division:

= 360 ÷ 8

= 45

To find out how many feet there are in 6 miles, we need to multiply the number of feet in one mile by 6:

= 6 miles x 5,280 feet/mile

= 31,680 feet

If Sylvester has 35 miniature cars, and Alice has 1/5 as many as Sylvester, we can find the number of miniature cars that Alice has by multiplying Sylvester's number by 1/5:

= 35 x 1/5

= 7

Thus,

Each group will get 45 unitcubes.

There are 31,680 feet in 6 miles.

Alice has 7 miniaturecars.

The height of Gateway Arch shown on Missouri quarter is 630 feet or 7,560 inches.Find how many 4-inch stacks of quarters make up the height of Gateway Arch.If there are 58 quarter in a 4-inch stack, how many quarters high is the arch?

Answers

To do this you want to divide 7560 by 4. This leaves you with 1845. Therefore, you need 1845 4-inch stacks to build that high. You are not done though. You need to multiply 1845 by 58. This gives you 107,010. It would take 107,010 quarters to get to the top.
