Question

The total surface area of cube is 600sqcm find the side of cube and its lateral surface area

Answer 1

Answer:

TSA OF CUBE=6a^2

600/6=a^2

a=10 cm

lateral surface area of cube =4a^2

                                             =4 x (10)^2

                                              =400 sq cm

Step-by-step explanation:

Answer 2

Step-by-step explanation:

TSA = 600cmsq

${6a}^{2} = 600 \\ {a }^{2} = 600 \div 6 \\ {a }^{2} = 100 \\ a = \sqrt{100} \\ a = 10 \: it \: is \: the \: side \: of \: the \: cube \\ \\ lateral \: surface \: area \: of \: cube = \: {4a}^{2} \\ {4 \times 10 }^{2} \\ 4 \times 100 \\ = 400 {cm}^{2}$
