Question

If the total surface area of a cube is 302.46 in, which best decribes the length of the side of the cube

Answer 1

Answer:

The length of the side of the cube is 7.1 cm

Step-by-step explanation:

Let the side of the cube be $x$

Given, Total Surface Area,TSA of Cube = $302.46cm^{2}$

We know that, The TSA of a cube = $6a^{2}$, where a is the side of the cube

                   Now,  302.46 = $6x^{2}$ (we have taken the side as x)

                           =>    $x^{2}$     =  $\frac{302.46}{6}$

                           =>    $x^{2}$     = $50.41$

                           =>    $x$      = $\sqrt{50.41}$

                               ∴  $x$  = 7.1 cm
