Step-by-step explanation:
Volume of a rectangular prism = Length * Width * Height
Volume of the rectangular prism = 
Length of the prism = 18cm
Width of the prism = 11cm
We need to find the Height of the Prism,
For that first make the Height as subject of the equation,
Height = [Volume of the rectangular prism/(Length * Width)]
=
/(18cm*11cm)
=
/
=
Therefore,
Answer is A. 12
Answer:
28 short-sleeved shirts were sold and 23 long-sleeved shirts were sold.
Step-by-step explanation:
We can solve this question by a system of equations.
I am going to say that:
x is the number of short-sleeved shirts sold.
y is the number of long-sleeved shirts sold.
A department store sold 51 shirts one day.
This means that 
All short-sleeved shirts cost $14.00 each and all long-sleeved shirts cost $23.00 each. Total receipts for the day were $921.00.
This means that

How many of each kind of shirt were sold?
We have to solve the system of equations.
