Question

Find the side of a cube with surface area of 150cm square

Answer 1

Answer:

5 cm

solution,

Surface area= 150 cm^2

Side of a cube(a)=?

Now,

$surface \: area \: of \: cube = 6 {a}^{2} \\ or \: 150 = 6 {a}^{2} \\ or \: {a}^{2} = \frac{150}{6} \\ or \: {a}^{2} = 25 \\ or \: a = \sqrt{25} \\ or \: a = \sqrt{ {(5)}^{2} } \\ a = 5 \: cm$

Hope this helps...

Good luck on your assignment..
