A rectangular prism has a length of 20 in., a width of 2 in., and a height of 314 in.
Novay_Z [31]
First solve the volume of the prism
V = l x w x h
where l is the length
w is the width
h is the hieght

V = 20 x 2 x 314
V = 12560 cu in

then solve the volume of the cube
V = e^3
V = 14^3
V = 2774 cu in

number of cube = 12560 / 2774
number of cube = 4 cubes

Place value is important to know when you are talking about prices. What items have prices that are in the hundreds of dollars?
Rufina [12.5K]

In math, every digit in a number has a place value.

<h3>What is place value?</h3>

Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.

For example, the place value of 7 in 3,743 is 7 hundreds or 700. However, the place value of 7 in 7,432 is 7 thousands or 7,000. Here, we can see that even though the digits are same in both the numbers, it’s place value changes with the change in it’s position.

The place value of a digit increases by ten times as we move left on the place value chart and decreases by ten times as we move right.  

From the question;

Prices for items in the value of hundreds

  • A smartphone - $100
  • Nike Jordan's - $156

Prices for items in the value of thousands

  • A smart TV - $1,500
  • A MacBook Pro - $2,550

Prices for items in the value of ten thousands

  • A New York city apartment - $10,000
  • A 2020 Toyota Corolla - $18,500
