Question

total surface area of a cube is 2400 cm² what is the length of a cube​

Answer 1

Answer:

Step-by-step explanation:

Given, area = 2400 sq.cm. We know, Length of edge of cube = √(A/6) = √(2400/6) = √400 = 20 cm.

Answer 2

Answer:

20cm

Step-by-step explanation:

TSA of cube = 6a² (where a = Side )

6a² = 2400

a² = 2400/6 = 400

a = 20cm

Hence, side of cube = 20cm

In cube all sides are equal

So (Side = Length = Breadth = Height)
