watts
Step-by-step explanation:
Answer:
The size of the cardboard should be 
Step-by-step explanation:
The diagram for this question is shown on the first uploaded image
The volume of the box is 
The length and the Width of the card is
L = W = Z
From the question we are told that 7 in squares were cut from each corner
So the length and the width of the box would be
L = W = (Z - 7)
And the height would be H = 7 in
Mathematically the volume of the box can be represented as

So the Volume would be
Substituting values


=> 

The volume of the cone is 3.14 x 14 x 14
Because then it would be easier to get an answer for a problem
divide 6000 by 3
6000 / 3 = 2000
so he can do 2000 sq ft per hour
