Question

Find the side of cube whose surface area is 5400sq centimetre

Answer 1

Answer:

30cm

Step-by-step explanation:

Surface area of square=6(a)sqr

6(a)^2=5400

a^2=900

a=30 cm (ans)

Answer 2

Answer:

⇒ 30 cm

Step-by-step explanation:

We know that:

Total surface area of the cube = 6(edge)²

Given, the surface area = 5400 cm²

So, 6(edge)² = 5400 cm²

6(edge)² = 5400

(edge)² = 5400/6

(edge)² = 900

(edge)² = 30²

edge = 30 cm

Hence, the side of the cube is 30cm
