Value? Unclear what you mean. i think you're asking to multiply x(5x)(3x+12). That won't give you a value, but rather an expression.
x*5x comes to 5x^2.
Then 5x^2(3x+12) comes to 15x^3 + 60x^2 (answer)
Here is your answer
REASON:
Formula for volume of rectangular prism= l×w×h
where, l=length=11cm
w=width=5cm
h=height= 6cm
So, volume= 11×5×6 cm^3
=330 cm^3

Step-by-step explanation:
Congruent means the same. You can prove that the two triangles are congruent by the measurements and also if they look the same. You can also see if parallelograms are congruent by seeing if they are the same. They also have to mirror the image of the other. Your welcome :)
