One way of calculating the volume would be to convert all of these measurements to decimal:
V = (18 in)(30 in)(8 in) = 4320 cubic in
Answer: The two equations that represent the conditions in the problems are 

Step-by-step explanation:
Since we have given that
Cost of 3 sparrows = $1
Cost of 2 turtle doves = $1
Cost of 1 dove = $2
Number of birds = 30
total cost = $30
So, Cost of s sparrows would be

Cost of t turtle doves would be
Cost of d doves would be

According to question, it becomes,

and

Hence, the two equations that represent the conditions in the problems are 

Answer:
The answer is 24
Step-by-step explanation:
The first step is to multiply 6x3=18 Then you multiply 4x3=12/2=6 Then you add 18+6=24 Your welcome :D
-5+3=-2-3+3=-2
Hope this helps
