Answer:

Step-by-step explanation:
we know that
In this problem ABCD is a rectangle
so
DC=AB
BC=AD
Let
BC ---> the length of rectangle
DC ---> the width of rectangle
we know that
The perimeter of rectangle is equal to

we have

so

simplify
----> equation A
----> equation B
substitute equation B in equation A

Solve for BC
Combine like terms

Divide by 3 both sides

<em>Find the value of DC</em>
----> 
Remember that
DC=AB
therefore

The answer is 343
Because volume is length x width x height which would be 7 x 7 x 7
