Hello!
To find the Volume of the Rectangular Prism, you'll need to multiply all of the measurements together. So you'll need to multiply 7, 9, and 11 together.
V=7*9*11
First, you'll need to multiply 7 and 9. Once you've multiplied 9 and 7 together, you should have 63. Now you should multiply 63 and 11 together. Once you've multiplied 63 and 11 together, you should have a Volume of 693
You should have a Volume of 693m³
I hope this helps!

Answer:
Step-by-step explanation:
The radical 
can be simplified by breaking it down into factors and removing the perfect squares from inside the radical.
25 is a perfect square and is 5 outside the radical.
is a perfect square and is x outside the radical.
is a perfect square and is 
outside the radical.
9a-5x
step by step explanation:
you can only add and subtract numbers that have the same variables.
12a and 3a are related because there variable is both a.
when u subtract 12a-3a you get the answer of 9a using subtraction.
7x and -2x are the second pair of related terms because they also have the same variable (x)
7x-2x is 5x using subtraction.
put the expression together:
9a-5x
hope this helps!
give me brainliest if it did plz
