A timber door is 200cm high, 80cm wide and 3.5cm thick. Calculate the surface area of the door. Hint - the awed is 33 960cm squared. I only need a diagram and working out ty

33 960 cm²

Step-by-step explanation:

Note the door has 6 surfaces.

The front and back have the same dimensions, that is

2 (200 * 80)

The top and bottom have the same dimensions, that is

2 (80 * 3.5)

The sides have the same dimensions, that is

2 (200 * 3.5)

Sum the area of the 6 faces for surface area of the door.

2 (200 * 80) + 2 (80 * 3.5) + 2 (200 * 3.5)

= 32000 + 560 + 1400

= 33960 cm²
