Answer:

400 cm²

Step-by-step explanation:

The new volume = 64,000 cm³

New length = (new volume)⅓ = (64,000)⅓ = 40cm

Old length = 40 cm ÷ 2 = 20 cm

Area = length² = 20² = 400 cm²

Answer:

400 cm²

Step-by-step explanation:

(side2/side1)³ = Volume2/Volume

2³ = 64000/X

X = 64000/8

X = 8000

Volume = side³

8000 = side³

Each side = 20

Area of a face = side²

= 20² = 400 cm²
