A box needs to be decorated to use as a prop in a play. The bottom and the back of the box do not need to be decorated. What is the surface area of the box that needs to be decorated?
Length is 27 width is 20 height is 20
(1 point)
1,080 cm
2, 960c * m ^ 2
O 1, 880c * m ^ 2
67c * m ^ 2
To find the surface area of the box that needs to be decorated, we need to calculate the surface area of the sides of the box.
The front face has a length of 27 and a height of 20.
The top face has a width of 20 and a length of 27.
The left and right faces both have a width of 20 and a height of 20.
Let's calculate the area of each face:
Front face: 27 * 20 = 540 cm^2
Top face: 20 * 27 = 540 cm^2
Left face: 20 * 20 = 400 cm^2
Right face: 20 * 20 = 400 cm^2
To find the total surface area of the box that needs to be decorated, we add up the areas of these four faces:
540 + 540 + 400 + 400 = 1,880 cm^2
Therefore, the surface area of the box that needs to be decorated is 1,880 cm^2.
