Question

    A rectangular prism has a length of 2 1/2 meters, a width of 4 meters, and a height of 2 1/4 meters.

Answer 1

Answer:

20

Step-by-step explanation:

put all in improper fractions

9/4

4/1

5/2

then multiply the length and the width

divide the product by the height

then, put it in mixed fraction form

Answer 2

First we need to convert our fractions into decimals, it's just a lot easier to work with.
2 1/2 is equal to 2.5
2 1/4 is equal to 2.25
Then we plug our numbers into the formula used to find the volume of a rectangle:
V=L*W*H
Volume equals Length times Width times Height.
V=2.5*4*2.25
V=22.5
22.5 is already in decimal form, or if you'd rather have a mixed number, your answer is 22 $\frac{1}{2}$
