Answer:
Step-by-step explanation:
Given data
breadth=9 in
Length=11 in
Now a square of side x is cutted for each corner such that the cardboard is made into a open-top box with
length=11-2x
breadth=9-2x
height=x
Here substract 2x because from both sides of length and breadth x units are reduced.
therefore volume of new open-top box is
Volume(v)=
The length of concrete patio is 6.5 feet which is less than given 7 foot picnic table. So the concrete slab is not enough to fit a 7 foot picnic table
<em><u>Solution:</u></em>
Given that concrete patio is feet wide
Area of concrete patio = square feet
Therefore,
Let us find the length of concrete patio
Concrete patio is usually of shape rectangle
Area of concrete patio = length x width
Therefore length of concrete patio is 6.5 feet
So it cannot fit the 7 foot picnic table. Since the length of concrete patio is 6.5 feet which is less than given 7 foot picnic table
