Question

Find the length of the side of a cube whose total surface area measures 600 sq cm.​

Answer 1

total surface area =6 × side ^2

but given =600cm^2

so ,

let the side be x

600 =6×x^2

6×x^2=600

x^2=600/6=100

x^2=100

therefore x=underoot 100 which is equals to 10

so . side of the cube is 10cm
