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 ares of the box that needs to be decorated?
To find the surface area of the box that needs to be decorated, we need to calculate the area of the front, the two sides, and the top.
Assuming the box is rectangular and its dimensions are given as:
Length: 20 cm
Width: 20 cm
Height: 27 cm
The area of the front (which is also the same as the area of the back) is:
20 cm * 27 cm = 540 cm^2
The area of each side is equal to the product of the length and height:
20 cm * 27 cm = 540 cm^2 (for each side)
The area of the top is equal to the product of the length and width:
20 cm * 20 cm = 400 cm^2
Thus, the total surface area of the box that needs to be decorated is:
Front + 2 Sides + Top = 540 cm^2 + 540 cm^2 + 400 cm^2 = 1480 cm^2
