Answer:

120.42 cm²

Step-by-step 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
