Answer:
Step-by-step explanation:
Given that,
Length of the prism, 
The breadth of the prism, 
The height of the prism, h = 12 in
We need to find the volume of the prism. The formula for the volume of a rectangular prism is given by :
Put all the values,
So, the volume of the rectangular prism is equal to 
.
Length of room = area / width
Length of room = 56/7 = 8 feet.
She will need 7 + 7 + 8 + 8 = 30 feet of border.
