To find the surface area of the box that needs to be decorated, we need to find the area of the front and the top of the box.
Area of the front:
= 27 cm * 20 cm
= 540 cm^2
Area of the top:
= 27 cm * 20 cm
= 540 cm^2
Total surface area of the box that needs to be decorated:
= Area of the front + Area of the top
= 540 cm^2 + 540 cm^2
= 1080 cm^2
Therefore, the correct answer is:
a. 1080 cm^2
Area of the front:
= 27 cm * 20 cm
= 540 cm^2
Area of the top:
= 27 cm * 20 cm
= 540 cm^2
Total surface area of the box that needs to be decorated:
= Area of the front + Area of the top
= 540 cm^2 + 540 cm^2
= 1080 cm^2
Therefore, the correct answer is:
a. 1080 cm^2
