h=67l=34w=44

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=34, the width w=44, and the height h=67 into the formula.

2⋅34⋅44+2⋅34⋅67+2⋅44⋅67

Multiply 2 by 34.

68⋅44+2⋅34⋅67+2⋅44⋅67

Multiply 68 by 44.

2992+2⋅34⋅67+2⋅44⋅67

Multiply 2 by 34.

2992+68⋅67+2⋅44⋅67

Multiply 68 by 67.

2992+4556+2⋅44⋅67

Multiply 2 by 44.

2992+4556+88⋅67

Multiply 88 by 67.

2992+4556+5896

2992+4556+5896

Add 2992 and 4556.

7548+5896

Add 7548 and 5896.
