Question

the total surface area of cube is 54cm square. What is the length of its sides?
6(a)²=54
a²=54/6
a=9root
a=3
Hence,the length of its sides are 3cm​

Answer 1

Answer:

The total surface area of cube = 6a²

Total surface area = 54 cm²

Therefore

54 = 6a²

54/6 = a²

9 = a²

3 cm = a

Therefore the length of the side is 3 cm
