Answer:
Volume = 6048 
Step-by-step explanation:
Volume is the capacity of substance that a given measuring object can contain. It can be determined as;
Volume = length x width x height
In the given question, the refrigerator has an internal dimensions 18 inches, 14 inches and 24 inches.
The volume of the refrigerator can be determined as;
Volume = 24 x 14 x 18
= 6048
Volume = 6048
Thus, the internal volume of the refrigerator is 6048 cubic inches.
Answer:
Integers and polynomials are both <u>closed </u>under addition, subtraction, and multiplication; however, operations on polynomials <u>can sometimes be open </u>while operations on integers <u>produce irrational results
</u>.
Step-by-step explanation:
Closed means that addition, subtraction, and multiplication of integers gives as result a new integer; and addition, subtraction, and multiplication of polynomials gives as result a new polynomial.
Operations on polynomials can sometimes be open, like in division.
Operations on integers can produce irrational results
, for example, dividing 11 by 9.
