Answer: 76 square centimeters
Explanation:
Since the dimensions are halved, we divide the length, the width and the height by 2. So, here are the new dimensions
length = 4 cm
width = 5 cm
height = 2 cm
Hence the surface area is given by
Surface area = 2[(length)(width) + (length)(height) + (width)(height)]
= 2[4(5) + 4(2) + 5(2)]
= 2[20 + 8 + 10]
= 2(38)
Surface area = 76 square centimeters
