Madelyn had a square piece of cardboard that 10 inches in length. She cut one 3-inch square from each corner, as shown below. Please show your work!

Why don't you just say what you want to do?
Figure the volume of the box? the surface area? cost using given data?

## Ac = 4(3*3) = 36 in^2. = Area cut.

Ar = Area remaining.
Ac + Ar = 10^2 = 100 in^2.
36 + Ar = 100,
Ar =

## so basically henry2, like what herny said to do but subtract 100-36=64

AR=64 because 64+36=100 that easy Hope this helped Take care and God bless.

## I drew a square of size 10

3 units from each edge, I drew a dotted line to show where to fold it.
I folded up the sides.

Now what?

## the base is a 4x4 square

there are 4 sides, each 3x4
so add them all up, right?

## To find the area of the resulting shape after cutting off the corners, you can follow these steps:

Step 1: Find the new length of each side of the square by subtracting twice the length of the cut-out square from the original length of the square.
New Side Length = Original Side Length - 2 * Cut-out Square Length

In this case, the original side length is 10 inches, and the cut-out square length is 3 inches.
New Side Length = 10 - 2 * 3

Step 2: Calculate the area of the resulting shape by squaring the new side length.
Resulting Shape Area = New Side Length * New Side Length

Now let's calculate the values:

Step 1: New Side Length = 10 - 2 * 3 = 10 - 6 = 4 inches

Step 2: Resulting Shape Area = 4 * 4 = 16 square inches

Therefore, the resulting shape after cutting off the corners has an area of 16 square inches.
