Question

find the side of cube whose total surface area is 1350cm²​

Answer 1

Step-by-step explanation:

total surface area of cube = 6 * l^2 or 6 *( side)^2

1350 = 6 * l^2

1350 / 6 = l^2

225 = l^2

l ( side) = 15 cm

Answer 2

Answer:The answer is 15cm

Step-by-step explanation:

Given, the total surface area of the cube is 1350 cm²

Let, the side of the cube is a cm

We know that, the total surface area = 6a² cm²

Then, 6a² = 1350

⇒ a² = 1350/6

⇒ a = √225

⇒ a = 15

∴The side of the cube is 15 cm
