Given:
There is a box without a lid.
The base is 4 feet by 3 feet
And the height = 2 feet
We will find the number of square feet of cardboard to make the box
So, we will find the lateral area + base area
The lateral area = perimeter of the base times the height
So, the lateral area =
[tex]2(4+3)*2=28\text{ }ft^2[/tex]
The area of the base = 4 x 3 = 12 sqaure feet.
So, the cardboard area = 28 + 12 = 40 square feet.
So, the answer will be 40 sqaure feet
