A box needs to be decorated to use as a prop in a play. The bottom in the back of the box do not need to be decorated. What is the surface area of the box that needs to be decorated? The front is 27 cm both sides are 20 cm, the box is rectangular
To find the surface area of the box that needs to be decorated, we need to calculate the area of the front and both sides.
The front of the box has dimensions of 27 cm by 27 cm, so the area is 27 cm * 27 cm = 729 cm^2.
Both sides of the box have dimensions of 20 cm by 27 cm, so the area of each side is 20 cm * 27 cm = 540 cm^2.
There are two sides, so the total area of both sides is 540 cm^2 + 540 cm^2 = 1080 cm^2.
Therefore, the total surface area of the box that needs to be decorated is 729 cm^2 (front) + 1080 cm^2 (sides) = 1809 cm^2.
