Question

find the length of the side of a cube whose total surface area measure 600 CM square

Answer 1

T.S.A. of a cube= 6 × side × side
600= 6× side × side
side × side= 600÷6
side × side= 100
side= 10 cm
i.e length= 10 cm

Answer 2

give surface area of the cube=600

surface area of a cube is
$6a {}^{2}$
$so \: 6a {}^{2} = 600$
${a}^{2} = 600 \div 6 \\ a = \sqrt{100 } \\ a = 10$
