<h3>Volume of solids</h3>
The formula for calculating the volume of a solid ie expressed as:
V = lwh
l is the length
w is the width
h is the height
For the given figure;
Volume = (11 * 2 * 3) + (2 * 3 * 4)
Volume = 66 + 24
Volume = 90 square cm
The required volume of a solid is 90 cubic cm

Answer:
Multiply 20 by 14.5 and you get the total number of cash, and when the two people enter, add 4 and 5 to that total number, giving you a new total, then divide that new total by 22 because there are now 22 people in the room.
Step-by-step explanation:
So basically what you would is u would plug the first equation into the second equation. -5x+21=4x+6
-21 -21
-5x=4x-15
-4x -4x
-9x=-15
-9x/-9=15/-9
x=-1.66
then you would plug x back into the equation to get your y value
y=4(-1.66)+6
y=6.64+6
y=12.64
