Question

The total surface area of cube is 486 cm2 find its lateral surface area

Answer 1

Answer:

324 cm^2

Step-by-step explanation:

6a^2=total surface area

6a^2=486

a^2=81

a=√81

a=9 cm

lateral surface area=4a^2

=) 4*9*9

=) 324 cm^2

Answer 2

Given:

Total surface area = 486cm²

To Find:

Lateral surface area

Explanation:

Formula for the Total Surface Area of the cube = 6a²

Now using this formula we get

6a²=total surface area

6a²=486

a²=(486/6)

a²=81

a=√81

a=9 cm

lateral surface area=4a²

4×9×9

324 cm²

Answer =  324 cm²
