Question

find the side of a cube whose surface area is600square centimeter

Answer 1

Given : -
Total surface area = 600 cm square

$6 {(side)}^{2} = 600 \\ \\ {(side)}^{2} = \frac{600}{6} \\ \\ {(side)}^{2} = 100 \\ \\ side = \sqrt{100} \\ \\ side = 10cm$

Answer 2

here is the answer
$6 \times (side)^{2} = 600cm {}^{2} \\ (side ) {}^{2} = \frac{600}{6} \\ (side) {}^{2} = 100 \\ side = \sqrt{100} \\ side = 10cm$
