Answer:
36 cm³
Step-by-step explanation:
Volume of rectangular prism =( L * B * H) or (area * height)
= 12 cm² * 3 cm
= 36 cm³
For this case we must factor the following quadratic expression:
To factor, we must find two numbers that when multiplied give as result +9 and when added or subtracted give as result -6.
These numbers are:
-3 and -3
So, we have:
