Question

Find the side of a cube whose surface area is 3600 cm2.​

Answer 1

Here the surface area of a cube is given to be 3600 cm²

We have to find the side of the cube

Total surface area = 6a², where a is the side of the cube

                  3600 = 6a²

                       a² = 3600/6

                       a² = 600

                       a = √600

                      a = 24.49

                         ≈ 24.5 cm

Hence, the side of the cube will be approximately 24.5 cm

Answer 2

The given data in the question is as below

The surface area of cube is $3600$ $cm^{2}$

We have to find the side of cube

Let side of cube be $x$

Surface area of cube =$6 \times (side)^{2}$

                           $3600$=$6\times(side)^{2}$

Dividing $3600$ by $6$ it get $600$

                           $\frac{3600}{6} =(side)^{2}$

                            $600=(side)^{2}$

Taking square root of $600$

                        $side=\sqrt{600}$

                        $side=24.4948$ $cm$

Therefore, side of a cube is equal to $24.4948 cm$
