h=66l=660w=1in

The surface area of a box is equal to the sum of the areas of each side of the box.

2⋅(length)⋅(width)+2⋅(length)⋅(height)+2⋅(width)⋅(height)

Substitute the values of the length l=660, the width w=1, and the height h=66 into the formula.

2⋅660⋅1+2⋅660⋅66+2⋅1⋅66

Multiply 2 by 660.

1320⋅1+2⋅660⋅66+2⋅1⋅66

Multiply 1320 by 1.

1320+2⋅660⋅66+2⋅1⋅66

Multiply 2 by 660.

1320+1320⋅66+2⋅1⋅66

Multiply 1320 by 66.

1320+87120+2⋅1⋅66

Multiply 2 by 1.

1320+87120+2⋅66

Multiply 2 by 66.

1320+87120+132

1320+87120+132

Add 1320 and 87120.

88440+132

Add 88440 and 132.
