Answer:
Assuming you mean a rectangular prism, cube, or triangular prism,the volume would be 384.
Step-by-step explanation:
Well volume for those two shapes could be b*h
SO base times height is always gonna give you volume for most shapes
Answer:
Sam
30
Step-by-step explanation:
Sam made a mistake when he said 
. The steps should have been:
You are supposed to square 5 first before multiplying 2. Sam multiplied by 2 first. The correct answer is 30.
The correct answers are A and B.

Answer:
?? = 900
Step-by-step explanation:
Solve algebraically
let x be ball and y be cube
x + y = 100
x - y = 80
xy = ??
We can solve by elimination. Eliminate one of the variables by adding OR subtracting the entire equations. I will add.
. x + y = 100
<u>+ x - y = 80</u> y + - y = y - y = 0; The variable is eliminated
. 2x = 180 Divide both sides by 2 to isolate x
. x = 90
Substitute x = 90 into one of the equations.
x + y = 100
90 + y = 100 Isolate y by subtracting 90 from both sides
y = 100 - 90
y = 10
Find xy = ?? by substituting y for 10 and x for 90.
xy = (90)(10) = 900
Therefore the value of ?? is 900.
The angles 1 and 2 are right angles.
As stated in the question line l is perpendicular to line m and perpendicular lines create right angles
Hope this helps :)
