Answer:
120.42 cm²
Explanation:
Let's start by finding the length of one side
Volume of a cube = side length³
90cm³=side length³
side length = 4.48 (rounded to two decimal places)
Now we find the surface area
Surface area = 6(area of one side)
Surface area = 6(side length²)
Surface area = 6(4.48²)
Surface area = 6(20.07)
Surface area = 120.42 cm²
