A rectangular prism has a length of 8 cm, a width of 10 cm, and a height of 4 cm. The dimensions are to be halved to create a reduction of the prism. What is the surface area of the reduced prism? Enter your answer in the box.

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
